This is important to fix the rendering of userspace applications that does frontbuffer rendering and notify driver about dirty areas but do not set any dirty clips. With this we don't need to worry about to check and mark the whole area as damaged in page flips. Another important change here is the move of drm_atomic_add_affected_planes() call, it needs to called late otherwise the area of all the planes would be added to pipe_clip and not saving power.
