If the fb format is YUV, enable the plane CSC mode bits
for the conversion.
v2: Addressed review comments from Shashank Sharma
Alignment issue fixed in i915_reg.h
v3: Adding Reviewed By from Shashank Sharma
v4: Rebased the patch. As part of rebasing, re-using
the color series defines which are already merged.
plane_state->base.color_encoding might not be set for
NV12. For now, just using PLANE_COLOR_CSC_MODE_YUV709_TO_RGB709
in glk_plane_color_ctl if format is NV12.
v5: Added reviewed by from Juha-Pekka Heikkila
v6: Rebased the series
