Add an option to indicate that the video driver should setup a SimpleFB node that passes the video framebuffer initialized by U-Boot to the operating system kernel.
Currently only the Allwinner DE1 driver uses this option, and the definition of this option in the sunxi-common.h config header is converted to an imply of this option from CONFIG_VIDEO_SUNXI.
Signed-off-by: Icenowy Zheng icenowy@aosc.io --- Changes in v5: - Convert Allwinner DE1 to use the option. Changes in v4: - Remove the dependency of VIDEO_DT_SIMPLEFB.
