drm/i915/color: move check of gamma_enable to specific func/platform
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] Signed-off-by: Swati Sharma <swati2.sharma@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191009065542.27415-3-swati2.sharma@intel.com
