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

With this we will expose support for post csc lut but corresponding handling in
driver is added later in the series. Would be good to move this after patch 8.
Please ignore the earlier comment, enabling of SDR planes is done in last patch
so this should be fine. We are good.
Thank you, Uma, for looking into the patch. Can I consider your RB for
v2 of the patch.
