Add Board Enable for ASUS Vintage 2 PH1 (P5LD2-MQ).

ASUS Vintage 2 PH1 barebone systems have a mainboard from the P5LD2 series,
namely the P5LD2-MQ (although it is labeled V2-PH1). Pin 16 GPIO needs to
be raised to enable write/erase like on other boards of the series.
NB: it uses a ICH7DH southbridge and hence requires different PCI IDs.
