description:
Allow the graphic driver to be the kernel's console.
Match either from the allwinner,pipeline entry in the simple-framebuffer
fdt entry, or from console= from the command line.
console=fb0 and console=fb1 selects display backend unit 0 or 1 respectively;
console=fb selects the first activated display backend.
