mainboard/asus: Add F2A85-M PRO variant to F2A85-M.

Status:
- The primary PCIe 16x slot works:
  It was tested with a GPU compatible with nouveau
- USB and audio are not very reliable
- The ethernet card is not seen with lspci
- The secondary pcie16x slot isn't working:
  When plugging a GPU inside, it's not seen with lspci
- SATA works: The board fully boots GNU/Linux
- Serial doesn't work
- Populating the RAM slots might have to follow
  the recommended memory configuration that is described
  in the mainboard manual in order to be able to boot.

Note that when running the shutdown command, the default
boot firmware will rewrite part of the boot flash before
powering off the machine.

Flashing coreboot internally from the default boot fimrware can
still work, if the power plug is removed after running flashrom.
