From: Ville Syrjälä <ville.syrj...@linux.intel.com>
Supposedly both src coordinates have to even when doing 90/270
degree rotation with RGB565. This is definitely true for the
X coordinate (we just get a black screen when it is odd). My
experiments didn't show any misbehaviour with an odd
Y coordinate, but let's trust the spec and reject that one
as well.
v2: Ignore ccs hsub/vsub
