mainboard/asus/p3b-f: Reintroduce as variant of p2b

Fold this last ASUS 440BX board into the P2B family, while bringing in
some changes:

- Devicetree becomes overridetree.
- Remove non-existent IR device and disable ACPI device on Super I/O to
  match OEM firmware.
- Add SB GPO settings from OEM firmware to devicetree. This disables
  the SPD enabling magic this board needs. By moving the enabling part
  to bootblock the hacky enable_spd hook can be eliminated.
- Initialize the serial port in bootblock, like the other boards.

Boot tested on hardware.
