Somewhere in the history of time, the initialisation of the PCI buses for the
AGP and PCI host bridges got mixed up in that the PCI host bridge was
creating an instance of the AGP PCI bus, and the AGP PCI bus was missing.

Swap the PCI host bridge over to use the correct PCI bus (including setting
the kMacRISCPCIAddressSelect register used by MacOS X) and add the missing
reference to the AGP PCI bus.
