Series fix broken state checker and enable state checker for icl+ | expand

Commit Message

Sharma, Swati2 Oct. 9, 2019, 6:55 a.m. UTC 
Moved common code to check gamma_enable to specific funcs per platform
in bit_precision func. icl doesn't support that and chv has separate
enable knob for CGM LUT.

v2:
-Simplified chv_gamma_precision() [Ville]
