drm/omap: use DRM_MODE_ROTATE_* instead of OMAP_DSS_ROT_*
At the moment the dispc driver uses a custom enum for rotation. Change
it to use the DRM's DRM_MODE_ROTATE_*.
Note that mirroring is at the moment handled as a separate boolean in
the dispc driver, so we only use the DRM_MODE_ROTATE_* values.
Note, DSS HW uses clockwise rotation, DRM counter-clockwise.
