mb/asus/p5q_pro: Add mainboard

This mainboard is quite similar to the p5qc. The main differences being a second
PEG slot, the IDE slot and being DDR2 only.

The following was tested:
- both PEG slots populated (coreboot sets legacy VGA decoding on the GPU in the
black slot)
- USB
- Ethernet NIC
- PS2 Keyboard
- COM1
- S3 resume
