uninorth: fix PCI and AGP bus mixup
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.
