The bootctl tests are currently disabled due to some image
incompatibilities: the multi UI uses one image and the simple UI uses a
different one.
Update the logic to switch between these logos when the layout changes.
For now, use the U-Boot logo in both cases.

an explicit call to scene_calc_dims() first. Drop it from both UIs.

All UI implementations will likely share a number of common elements, so
move these into a per-device uclass struct.
