[Intel-gfx] [v2 0/2] Fixed GC MAX register programming for gamma luts

[Uma Shankar]

Register offsets used to program GC max were not correct. This series
fixes the same, also limits the values to accurately clamp at 1.0.
Also added support to program EXT2 GC Max needed for values from 3.0
to 7.0. Limiting it again to 1.0 due to ABI limitations.

v2: Addressed Ville's review comments.
