The trick is not strictly necessary on SKL because the offset
registers allow more bits. But for FBC, doing this changes how the
hardware tracking works - it starts at the surface address we provide
- so there's a higher chance that the CRTC will be pointing to an area
of the frontbuffer that is ac
