From: Ville Syrjälä <ville.syrjala@linux.intel.com>
The sprite planes (in fact all display planes starting from gen4)
support 180 degree rotation. Add the relevant low level bits to the
sprite code to make use of that feature.
The upper layers are not yet plugged in.
v2: HSW handles the rotated buffer offset automagically
v3: BDW also handles the rotated buffer offset automagically
Testcase: igt/kms_rotation_crc

Propagate the error from intel_update_plane() up through
intel_plane_restore() to the caller. This will be used for
rollback purposes when setting properties fails.

Sprite planes support 180 degree rotation. The lower layers are now in
place, so hook in the standard rotation property to expose the feature
to the users.
