We made few changes in kms_color & other places to support Intel plane 
color pipeline includes Custom 1D LUT (gamma & degamma) and CTM 3x3.

Hope you are fine if I float my changes along with your patches as a new 
rev of this series (This series also needs a rebase). So that it would 
be easy to review all IGT changes present in single series.

Basic changes are available at try-bot (still need some cleanup): [1]
Please let me know if you wanna suggest another way.
