For reviewing (and bisect-ability) it would be easier to have this
squashed with omapdrm: allocate fbdev in TILER.

Another question:
Sebastian Reichel showed a rotated console on omap4 in his
fosdem presentation, so can we do it the same way?
As it rotated hdmi and lcd the same time it does not look like something
done in a lcd driver chip...
