From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
On certain platforms not all planes support the same set of
rotations/reflections, so let's use the per-plane property
for this.
This is already a problem on SKL when we use the legay cursor plane
as it only supports 0|180 whereas the universal planes support
0|90|180|270, and it will be a problem on CHV soon.
