This commit message is incorrect; it does not add the command line option. I'll send a v2.

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.
