Add an option to indicate that the video driver should setup a

Currently only the Allwinner DE2 driver uses this option.

Enables the code to pass the framebuffer to the kernel as asimple framebuffer in the device tree.The video output is initialized by U-Boot, and kept by thekernel.You should also remove it from the current users. It will generate a warning otherwise.
I think the only current user is DE1.
I was talking about configs/sunxi-common.h
Should I also convert DE1 to use this option in this patch?
That, or just make it a default to ARCH_SUNXI in that patch.
