drm/msm/gpu: Cancel idle/boost work on suspend
With system suspend using pm_runtime_force_suspend() we can't rely on
the pm_runtime_get_if_in_use() trick to deal with devfreq callbacks
after (or racing with) suspend. So flush any pending idle or boost
work in the suspend path.

drm/msm/gpu: Wait for idle before suspending
System suspend uses pm_runtime_force_suspend(), which cheekily bypasses
the runpm reference counts. This doesn't actually work so well when the
GPU is active. So add a reasonable delay waiting for the GPU to become
idle.
Alternatively we could just return -EBUSY in this case, but that has the
disadvantage of causing system suspend to fail.
v2: s/ret/remaining [sboyd], and switch to using active_submits count
to ensure we aren't racing with submit cleanup (and devfreq idle
work getting scheduled, etc)
v3: fix inverted logic

This doesn't go well (for example, GPU could be in 32b address mode

I'm not *quite* sure how we get into this state in the first place,

While we're at it, also add the information about whether the GPU is

Since commit
8f59ee9a570c ("drm/msm/dsi: Adjust probe order"), the
DSI host gets initialized earlier, but this caused unability to probe
the entire stack of components because they all depend on interrupts
coming from the main `mdss` node (mdp5, or dpu1).
To fix this issue, move mdss device initialization (which include irq
domain setup) to msm_mdev_probe() time, as to make sure that the
interrupt controller is available before dsi and/or other components try
to initialize, finally satisfying the dependency.

drm/msm: Allocate msm_drm_private early and pass it as driver data
In preparation for registering the mdss interrupt controller earlier,
move the allocation of msm_drm_private from component bind time to
msm_drv probe; this also allows us to use the devm variant of kzalloc.
Since it is not right to allocate the drm_device at probe time (as
it should exist only when all components are bound, and taken down
when components get cleaned up), the only way to make this happen is
to pass a pointer to msm_drm_private as driver data (like done in
many other DRM drivers), instead of one to drm_device like it's
currently done in this driver.
This is also simplifying some bind/unbind functions around drm/msm,
as some of them are using drm_device just to grab a pointer to the
msm_drm_private structure, which we now retrieve in one call.

drm/msm/gpu: Respect PM QoS constraints
Re-work the boost and idle clamping to use PM QoS requests instead, so
they get aggreggated with other requests (such as cooling device).
This does have the minor side-effect that devfreq sysfs min_freq/
max_freq files now reflect the boost and idle clamping, as they show
(despite what they are documented to show) the aggregated min/max freq.
Fixing that in devfreq does not look straightforward after considering
that OPPs can be dynamically added/removed. However writes to the
sysfs files still behave as expected.

drm/i915/dg2: Tile 4 plane format support
TileF(Tile4 in bspec) format is 4K tile organized into
64B subtiles with same basic shape as for legacy TileY
which will be supported by Display13.
v2: - Fixed wrong case condition(Jani Nikula)
- Increased I915_FORMAT_MOD_F_TILED up to 12(Imre Deak)
v3: - s/I915_TILING_F/TILING_4/g
- s/I915_FORMAT_MOD_F_TILED/I915_FORMAT_MOD_4_TILED/g
- Removed unneeded fencing code
v4: - Rebased, fixed merge conflict with new table-oriented
format modifier checking(Stan)
- Replaced the rest of "Tile F" mentions to "Tile 4"(Stan)
v5: - Still had to remove some Tile F mentionings
- Moved has_4tile from adlp to DG2(Ramalingam C)
- Check specifically for DG2, but not the Display13(Imre)
v6: - Moved Tile4 associating struct for modifier/display to
the beginning(Imre Deak)
- Removed unneeded case I915_FORMAT_MOD_4_TILED modifier
checks(Imre Deak)
- Fixed I915_FORMAT_MOD_4_TILED to be 9 instead of 12
(Imre Deak)
v7: - Fixed display_ver to { 13, 13 }(Imre Deak)
- Removed redundant newline(Imre Deak)
