The GFX controller is the internal graphics device used by the SoC (opposed to the one connected via the PCIe device and used by the host). This configures it with a framebuffer region and adds it to the command line so kernel boot messages appear on the display. Enabled for Romulus, Witherspoon, and the ASPEED AST2500 EVB.
