hw/i386/pc_piix: Make PIIX4 south bridge usable in PC machine
QEMU's PIIX3 implementation actually models the real PIIX4, but with different PCI IDs. Usually, guests deal just fine with it. Still, in order to provide a more consistent illusion to guests, allow QEMU's PIIX4 implementation to be used in the PC machine.
