From: James Ausmus <james.ausmus@xxxxxxxxx>
These fields have been deprecated and moved in ICL+. Stop setting the
bits.
They have moved to GAMMA_MODE and CSC_MODE, respectively. This patch
is just to stop incorrectly setting bits in PLANE_COLOR_CTL while
we're waiting for the new replacement functionality to be done.
v2: Drop useless comment, and change !(GEN >= 11) to (GEN < 11). (Ville)
v3: No changes
