Add support for ASUS F2A85-M board

The patch is based on Thatcher board. So far it boots Linux (3.2/3.7),
internal network adapter works, AHCI works. External PCI/PCIe slots
works too. Power management/ACPI seems to work.

Internal VGA works with dumped ROM (VGA/DVI), but lacks GART.

PCI pref devices are being relocated by Linux, reason unknown.

This is a good start.

USB and XHCI untested but visible.
