[Intel-gfx] [PATCH v2 0/9] Handle BPC for HDMI2.1 PCON without DSC1.2 sink and other fixes

[Ankit Nautiyal]

This series fixes issues faced when an HDMI2.1 sink that does not
support DSC is connected via HDMI2.1PCON. It also icludes other minor
HDMI2.1 PCON fixes/refactoring.

Patch 1-3 Have minor fixes/cleanups.
Patch 4-7 Pull the decision making to use DFP conversion capabilities
for every mode during compute config, instead of having that decision
during DP initializing phase.
Patch 8-9 Calculate the max BPC that can be sufficient with either
RGB or YCbcr420 format for the maximum FRL rate supported.

Rev2: Split the refactoring of DFP RG->YCBCR conversion into smaller
patches, as suggested by Jani N.
Also dropped the unnecessary helper for DSC1.2 support for HDMI2.1 DFP.

  drm/i915/dp: Reset frl trained flag before restarting FRL training
  drm/i915/dp: Add RGB to YCBCR conversion case in is_dp_ycbcr420 helper

    dp_dfp members
  drm/i915/dp: Handle BPP where HDMI2.1 DFP doesn't support DSC
  drm/i915/dp: Fix FRL BW check for HDMI2.1 DFP
