[v6 6/9] drm/i915/color: Add support for 1D LUT in SDR planes

[Chaitanya Kumar Borah <chaitanya.kumar.borah@intel.com>]

Extend the SDR plane color pipeline to post-CSC 1D LUT block.

v2:
 - In preparation of a simple pipeline
	[YUV Full/Limited -> RGB] -> [1D LUT]
   Drop pre-CSC LUT from the pipeline as it has no use in a YUV -> RGB
   pipeline. This makes the pipeline simple since the block lies between
   the YUV range correct block and Fixed function CSC. It can be added back
   when [RGB709 -> RGB2020] capability is added. Then it can be used for
   linearization.
