Add Dell Latitude E6430

This was only tested on the iGPU model, though a dGPU model does exist.
The vendor firmware used a 16KiB gbe.bin, which was modified with a
random MAC address as well as shrinking it to 8KiB. As with the E6400,
GRUB doesn't like the way the EC implements the keyboard controller and
thus GRUB payloads are disabled at this time. Suspend does not currently
work, and this is believed to be due to the EC controlling the DRAM
reset gate which is required to prevent DRAM from being reset on resume.

With some tweaks, the e6400-flash-unlock utility also works on this
system, though both flash chips can be accessed through removal of only
the keyboard.
