From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx>
Need to do this in order to support 90/270 rotated display.
v2: Pass in drm_plane instead of plane index to intel_obj_display_address.
v3:
* Renamed intel_obj_display_address to intel_plane_obj_offset.
(Chris Wilson)
* Simplified rotation check to bitwise AND. (Chris Wilson)
v4:
* Extracted 90/270 rotation check into a helper function. (Michel Thierry)
For: VIZ-4545
