drm/i915: Add 180 degree sprite rotation support
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 Cc: dri-devel@lists.freedesktop.org Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Sagar Kamble <sagar.a.kamble@intel.com> Reviewed-by: Imre Deak <imre.deak@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
