From: Uma Shankar <uma.shankar@xxxxxxxxx>
Add macros to define multi segmented gamma registers
V2: Addressed Ville's comments:
Add gen-lable before bit definition
Addressed Jani's comment
- Use REG_GENMASK() and REG_BIT()
V3: Addressed Ville's comments:
- Put comments at the end of line.
- Change the comment at start of ICL multisegmented gamma registers.
Added Ville's r-b
