staging: drm/omap: DMM based hardware scrolling console
Add support for YWRAP scrolling by shuffling pages around in DMM
instead of sw blits.
Note that fbcon only utilizes this mode if the y resolution is
divided evenly by the font height. So, for example, a 1920x1080
display using a 16 pixel tall font will not utilize this, but a
1280x1024 display would.
