drm/i915: Fix glk+ degamma LUT conversions
The current implementation of change_lut_val_precision() is just
a convoluted way of shifting by 8. Implement the proper rounding
by just using drm_color_lut_extract() and intel_color_lut_pack()
like everyone else does.
And as the uapi can't handle >=1.0 values but the hardware
can we need to clamp the results appropriately in the readout
path.
