[flashrom] [PATCH] Add support for ASUS M2V-MX board

[David Bartley]

The way I figured this out was by picking the chip closest to the BIOS
(the VT8237A southbridge) and inverting each of the GPIO lines one at
a time. The GPIO stuff was gleaned from the VT8237R datasheet since I
couldn't find the 'A one anywhere. All in all, a very fun and
educating experience; next step, coreboot!

On a related note, reading the flash back seems slightly broken;
sometimes the read gets a few bytes wrong.
