drm/i915/display/icl: Save Master transcoder in slave's crtc_state for Transcoder Port Sync
In case of tiled displays when the two tiles are sent across two CRTCs
over two separate DP SST connectors, we need a mechanism to synchronize
the two CRTCs and their corresponding transcoders.
So use the master-slave mode where there is one master corresponding
to last horizontal and vertical tile that needs to be genlocked with
all other slave tiles.
This patch identifies saves the master transcoder in all the slave
CRTC states. This is needed to select the master CRTC/transcoder
while configuring transcoder port sync for the corresponding slaves.
v6:
Rebase (manasi)
v5:
* Address Ville's comments
* Just pass crtc_state, no need to check GEN (Ville)
v4:
* Rebase
v3:
* Use master_tramscoder instead of master_crtc for valid
HW state readouts (Ville)
v2:
* Move this to intel_mode_set_pipe_config(Jani N, Ville)
* Use slave_bitmask to save associated slaves in master crtc state (Ville)

drm/i915: Restore full symmetry in i915_driver_modeset_probe/remove
Commit
2d6f6f359fd8 ("drm/i915: add i915_driver_modeset_remove()")
claimed removal of asymmetry in probe() and remove() calls, however, it
didn't take care of calling intel_irq_uninstall() on driver remove.
That doesn't hurt as long as we still call it from
intel_modeset_driver_remove() but in order to have full symmetry we
should call it again from i915_driver_modeset_remove().
Note that it's safe to call intel_irq_uninstall() twice thanks to
commit
b318b82455bd ("drm/i915: Nuke drm_driver irq vfuncs"). We may
only want to mention the case we are adding in a related FIXME comment

drm/i915/pmu: Support multiple GPUs
With discrete graphics system can have both integrated and discrete GPU
handled by i915.
Currently we use a fixed name ("i915") when registering as the uncore PMU
provider which stops working in this case.
To fix this we add the PCI device name string to non-integrated devices
handled by us. Integrated devices keep the legacy name preserving
backward compatibility.
v2:
* Detect IGP and keep legacy name. (Michal)
* Use PCI device name as suffix. (Michal, Chris)
v3:

drm/i915: Switch to using DP_MSA_MISC_* defines
Now that we have standard defines for the MSA MISC bits lets use
them on HSW+ where we program these directly into the TRANS_MSA_MISC

drm/i915/dp: Program an Infoframe SDP Header and DB for HDR Static Metadata
Function intel_dp_setup_hdr_metadata_infoframe_sdp handles Infoframe SDP
header and data block setup for HDR Static Metadata. It enables writing of
HDR metadata infoframe SDP to panel. Support for HDR video was introduced
in DisplayPort 1.4. It implements the CTA-861-G standard for transport of
static HDR metadata. The HDR Metadata will be provided by userspace
compositors, based on blending policies and passed to the driver through
a blob property.
Because each of GEN11 and prior GEN11 have different register size for
HDR Metadata Infoframe SDP packet, it adds and uses different register
size.
Setup Infoframe SDP header and data block in function
intel_dp_setup_hdr_metadata_infoframe_sdp for HDR Static Metadata as per
dp 1.4 spec and CTA-861-F spec.
As per DP 1.4 spec, 2.2.2.5 SDP Formats. It enables Dynamic Range and
Mastering Infoframe for HDR content, which is defined in CTA-861-F spec.
According to DP 1.4 spec and CEA-861-F spec Table 5, in order to transmit
static HDR metadata, we have to use Non-audio INFOFRAME SDP v1.3.

| [ Packet Type Value ] | [ Packet Type ] |

v2: Add a missed blank line after function declaration.
v3: Remove not handled return values from
intel_dp_setup_hdr_metadata_infoframe_sdp(). [Uma]
v9: Addressed review comments from Ville.
- Add BUILD_BUG_ON to check a changing of struct dp_sdp size.
- Change a passed size toward write_infoframe() for DP infoframe sdp
packet for HDR static metadata.

drm/i915/dp: Attach colorspace property
It attaches the colorspace connector property to a DisplayPort connector.
Based on colorspace change, modeset will be triggered to switch to a new
colorspace.
And in order to distinguish colorspace bwtween DP and HDMI connector, it
adds a handling of drm_mode_create_dp_colorspace_property() to
intel_attach_colorspace_property().
Based on colorspace property value create a VSC SDP packet with appropriate
colorspace. This would help to enable wider color gamut like BT2020 on a
