drm/i915: Use the per-plane rotation property

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.

v2: Use drm_plane_create_rotation_property() helper
v3: Drop the BIT(), use INTEL_GEN()
