mb/asus/p5gc-mx: Add mainboard

Tested to work:
* GPU (Nvidia gt210) in PCIe x16 slot;
* SATA;
* serial;
* 800MHz and 1067MHz FSB Core 2 Duo CPUs;
* ethernet;
* native VGA graphic init.

What does not work:
* resume from s3 suspend;
* superio hardware monitor (not initialised in coreboot).

Quirks:
* does not boot with just one dimm in slot B.
