commit 8b0d2f61545545ab5eef923ed6e59fc3be2385e0 upstream.

FB_DAMAGE_CLIPS is a plane property for damage handling. Its UAPI
should only use UAPI types. Hence replace struct drm_rect with
struct drm_mode_rect in drm_atomic_plane_set_property(). Both types
are identical in practice, so there's no change in behavior.
