From: Ville Syrjälä <ville.syrj...@linux.intel.com>
Use consistent bit definitions for the 10bit precision palette bits.
We just define these alongside the ilk/snb register definitions and
point to those from the ivb+ defines.
Also use the these appropriately in the LUT entry pack/unpack
functions.
