drm/amd/display: hook up DCN30 color blocks data to DTN log

Color caps changed between HW versions, which caused the DCN10 color
state sections in the DTN log to no longer match DCN3+ state. Create a
color state log specific to DCN3.0 and hook it up to DCN3.0+ and DCN3.1+
drivers.

rfc-v2:
- detail RAM mode for gamcor and blnd gamma blocks
- add MPC gamut remap matrix log

v3:
- read MPC gamut remap matrix in fixed 31.32 format
- extend to DCN3.0+ and DCN3.1+ drivers (Harry)
