drm/amd/display: Enable FPO for configs that could reduce vlevel

[Description]
- On high refresh rate DRR displays that support VBLANK naturally,
  UCLK could be idling at DPM1 instead of DPM0 since it doesn't use
  FPO
- To achieve DPM0, enable FPO on these configs even though it can
  support P-State without FPO
- Default disable for now, have debug option to enable

drm/radeon: Implement client-based fbdev emulation

Implement fbdev emulation on top of struct drm_client and its helpers.
Replaces ad-hoc interfaces for restoring and closing fbdev emulation with
per-client callbacks for hotplugging, restoring and unregistering.

A single function, radeon_fbdev_setup(), starts fbdev emulation after
the DRM device has been registered. Hence, fbdev acts like a regular
DRM client.

The setup call prepares the fbdev emulation and invokes connector
hotplugging. The first successful hotplug event initializes fbdev
emulation with a framebuffer, device file, etc.

Unregistering depends on the hotplug status. Fully initialized emulation
is cleaned up through drm_fb_helper_unregister_info() and fb_destroy.
For prepared-only setups, unregistering unprepares the emulation and
releases all resources. In both cases, fbdev emulation will be cleaned
up.

drm/amd/display/amdgpu_dm: Pass proper parent for backlight device registration v3

The parent for the backlight device should be the drm-connector object,
not the PCI device.

Userspace relies on this to be able to detect which backlight class device
to use on hybrid gfx devices where there may be multiple native (raw)
backlight devices registered.

Specifically gnome-settings-daemon expects the parent device to have
an "enabled" sysfs attribute (as drm_connector devices do) and tests
that this returns "enabled" when read.

This aligns the parent of the backlight device with i915, nouveau, radeon.
Note that drivers/gpu/drm/amd/amdgpu/atombios_encoders.c also already
uses the drm_connector as parent, only amdgpu_dm.c used the PCI device
as parent before this change.

Changes in v3:
Make amdgpu_dm_register_backlight_device() check bl_idx != 1 before
registering the backlight since amdgpu_dm_connector_late_register()
now calls it for _all_ connectors.

Changes in v2:
Together with changing the parent, also move the registration to
drm_connector_funcs.late_register() this is necessary because the parent
device (which now is the drm_connector) must be registered before
the backlight class device is, otherwise the backlight class device ends
up without any parent set at all.

This brings the backlight class device registration timing inline with
nouveau and i915 which also use drm_connector_funcs.late_register()
for this.

Note this slightly changes backlight_device_register() error handling,
instead of not increasing dm->num_of_edps and re-using the current
bl_idx for a potential other backlight device, dm->backlight_dev[bl_idx]
is now simply left NULL on failure. This is ok because all code
looking at dm->backlight_dev[i] also checks it is not NULL.

drm/amd/display/amdgpu_dm: Refactor register_backlight_device()

Refactor register_backlight_device():

1) Turn the connector-type + signal check into an early exit
condition to avoid the indentation level of the rest of the code

2) Add an array bounds check for the arrays indexed by dm->num_of_edps

3) register_backlight_device() always increases dm->num_of_edps if
amdgpu_dm_register_backlight_device() has assigned a backlight_dev to
the current dm->backlight_link[dm->num_of_edps] slot.

So on its next call dm->backlight_dev[dm->num_of_edps] always point to
the next empty slot and the "if (!dm->backlight_dev[dm->num_of_edps])"
check will thus always succeed and can be removed.

4) Add a bl_idx local variable to use as array index, rather then
using dm->num_of_edps to improve the code readability.

drm/amdgpu: Force signal hw_fences that are embedded in non-sched jobs

[Why]
For engines not supporting soft reset, i.e. VCN, there will be a failed
ib test before mode 1 reset during asic reset. The fences in this case
are never signaled and next time when we try to free the sa_bo, kernel
will hang.

[How]
During pre_asic_reset, driver will clear job fences and afterwards the
fences' refcount will be reduced to 1. For drm_sched_jobs it will be
released in job_free_cb, and for non-sched jobs like ib_test, it's meant
to be released in sa_bo_free but only when the fences are signaled. So
we have to force signal the non_sched bad job's fence during
pre_asic_reset or the clear is not complete.

Merge tag 'drm-habanalabs-next-2023-03-20' of https://git./linux/kernel/git/ogabbay/linux into drm-next

This tag contains habanalabs driver and accel changes for v6.4:

- uAPI changes:

  - Add opcodes to the CS ioctl to allow user to stall/resume specific engines
    inside Gaudi2. This is to allow the user to perform power
    testing/measurements when training different topologies.

  - Expose in the INFO ioctl the amount of device memory that the driver
    and f/w reserve for themselves.

  - Expose in the INFO ioctl a bit-mask of the available rotator engines
    in Gaudi2. This is to align with other engines that are already exposed.

  - Expose in the INFO ioctl the register's address of the f/w that should
    be used to trigger interrupts from within the user's code running in the
    compute engines.

  - Add a critical-event bit in the eventfd bitmask so the user will know the
    event that was received was critical, and a reset will now occur

  - Expose in the INFO ioctl two new opcodes to fetch information on h/w and
    f/w events. The events recorded are the events that were reported in the
    eventfd.

- New features and improvements:

  - Add a dedicated interrupt ID in MSI-X in the device to the notification of
    an unexpected user-related event in Gaudi2. Handle it in the driver by
    reporting this event.

  - Allow the user to fetch the device memory current usage even when the
    device is undergoing compute-reset (a reset type that only clears the
    compute engines).

  - Enable graceful reset mechanism for compute-reset. This will give the
    user a few seconds before the device is reset. For example, the user can,
    during that time, perform certain device operations (dump data for debug)
    or close the device in an orderly fashion.

  - Align the decoder with the rest of the engines in regard to notification
    to the user about interrupts and in regard to performing graceful reset
    when needed (instead of immediate reset).

  - Add support for assert interrupt from the TPC engine.

  - Get the reset type that is necessary to perform per event from the
    auto-generated irq_map array.

  - Print the specific reason why a device is still in use when notifying to
    the user about it (after the user closed the device's FD).

  - Move to threaded IRQ when handling interrupts of workload completions.

- Firmware related fixes:

  - Fix RAZWI event handler to match newest f/w version.

  - Read error cause register in dma core events because the f/w doesn't
    do that.

  - Increase maximum time to wait for completion of Gaudi2 reset due to f/w
    bug.

  - Align to the latest firmware specs.

- Enforce the release order of the compute device and dma-buf.
  i.e increment the device file refcount for any dma-buf that was exported
  for that device. This will make sure the compute device release function
  won't be called until the user closes all the FDs of the relevant
  dma-bufs. Without this change, closing the device's FD before/without
  closing the dma-buf's FD would always lead to hard-reset of the device.

- Fix a link in the drm documentation to correctly point to the accel section.

- Compilation warnings cleanups

- Misc bug fixes and code cleanups
