drm/i915: Clean up 12.4bit precision palette defines
Use consistent bit definitions for the 12.4bit precision palette bits.
We just define these alongside the ilk/snb register definitions and
point to those from the icl+ superfine segment defines (and we also
already pointed to them from the ivb+ precision palette defines).
Also use the these appropriately in the LUT entry pack/unpack
functions.
