[PATCH v3 9/9] drm/amd/display: hook up DCN20 color blocks data to DTN log

Tue Nov 28 17:52:57 UTC 2023
Color caps changed between HW versions, which caused the DCN10 color
state sections in the DTN log to no longer match DCN2+ state. Create a
color state log specific to DCN2.0 and hook it up to DCN2 family
drivers. Instead of reading gamut remap reg values, display gamut remap
matrix data in fixed 31.32.
