- rotated text console
- bitmap display (BMP format)

More can be added as additional boards are ported over to use driver model
for video.

The name 'video' is chosen for the uclass since it is more generic than LCD.
Another option would be 'display' but that would introduce a third concept
to U-Boot which seems like the wrong approach.

The existing LCD and video init functions are not needed now, so this uclass
makes no attempt to implement them.
