drm/amd/display: add plane shaper LUT support
Map DC shaper LUT to DM plane color management. Shaper LUT can be used
to delinearize and/or normalize the color space for computational
efficiency and achiving specific visual styles. If a plane degamma is
apply to linearize the color space, a custom shaper 1D LUT can be used
just before applying 3D LUT.
v2:
- use DPP color caps to verify plane 3D LUT support
- add debug message if shaper LUT programming fails
v4:
- remove helper to check 3D LUT color caps (Harry)
- update desc of lut3d-setup helper from MPC to DPP
v5:
- remove color_mgmt_changed check that prevents color updates (Joshua)
