Subject: drm/amd/display: Support plane-level gamut remap in DM
Git-commit: 44efb78410820045992a7d7f550f718c62d0ffa8
Patch-mainline: v5.8-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

[Why]
Plane-level gamut remap is not enabled in DM, which is necessary to
support CTM as a plane-level property.

[How]
Enable gamut remap in DM.
