drm/i915/color: Downscale degamma lut values read from hardware
For MTL and beyond, convert back the 24 bit lut values
read from HW to 16 bit values to maintain parity with
userspace values. This way we avoid pipe config mismatch
for pre-csc lut values.
v2: Add helper function to downscale values (Jani)
