drm/amd/display: add CRTC gamma TF support
Add predefined transfer function programming. There is no post-blending
out gamma ROM for hardcoded curves, but we can use AMD color modules to
program LUT parameters from pre-defined coefficients and an empty
regamma LUT (or bump up LUT parameters with pre-defined TF values).
v2:
- update crtc color mgmt if regamma TF differs between states (Joshua)
- map inverse EOTF to DC transfer function (Melissa)
v3:
- update AMDGPU TF list
v4:
- update comment regarding regamma behavior
