drm/amd/display: add plane 3D LUT support
Wire up DC 3D LUT to DM plane color management (pre-blending). On AMD
display HW, 3D LUT comes after a shaper curve and we always have to
program a shaper curve to delinearize or normalize the color space
before applying a 3D LUT (since we have a reduced number of LUT
entries).
In this version, the default values of 3D LUT for size and bit_depth are
17x17x17 and 12-bit, but we already provide here a more generic
mechanisms to program other supported values (9x9x9 size and 10-bit).
v2:
- started with plane 3D LUT instead of CRTC 3D LUT support
v4:
- lut3d_size is the max dimension size instead of # of entries
