[Intel-gfx] [v5 0/2] Enable Plane Input CSC for ICL

[Uma Shankar]

This patch series enables plane input csc feature for
ICL. This is needed for YUV to RGB conversion on bottom
3 planes on ICL, other planes are handled in the legacy
way using fixed function hardware.

This series enables color conversion for Full Range YUV data,
limited range handling will be done as a separate patch.

v2: Separated the patch into 2 parts as per Maarten's comments.
Addressed Ville and Maarten's review comment.

v3: Redesigned the register macro definition as per Matt's comment.
Addressed Maarten's review comment.

v4: Added support for Limited Range Color Handling.

v5: Fixed Matt and Maarten's review comments.

Note: This is currently untested and floated to get feedback
on the design and implementation for this feature. In parallel,
I will test this on actual ICL hardware and confirm with planar
formats.
