drm/amd/display: allow newer DC hardware to use degamma ROM for PQ/HLG

Browse Source 
Need to funnel the color caps through to these functions so it can check
that the hardware is capable.

v2:
- remove redundant color caps assignment on plane degamma map (Harry)
- pass color caps to degamma params

v3:
- remove unused color_caps parameter from set_color_properties (Harry)
