drm/amd/display: Implement custom degamma lut on dcn
[Why]
Custom degamma lut functions are a feature we would
like to support on compatible hardware
[How]
In atomic check, convert from array of drm_color_lut to
dc_transfer_func. On hardware commit, allow for possibility
of custom degamma. Both are based on the equivalent
regamma pipeline.
