[PATCH 0/2] drm/amd/display: follow-up fixes for LUT segmentation

Extend halving distribution for all curves/custom-LUT in a
encode-to-linear operation, not only PQ/SRGB. This fixes failures in IGT
kms_colorop test after [1]. Also use the CM3 degamma helper that
translates curves to hw points for DCN30-based family, not only DCN32,
since the banding issue is present on both.
