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.
