Convert PowerPC AIM PCI and nexus busses to standard OFW bus interface. This

simplifies certain device attachments (Kauai ATA, for instance), and makes
possible others on new hardware.

On G5 systems, there are several otherwise standard PCI devices
(Serverworks SATA) that will not allow their interrupt properties to be
written, so this information must be supplied directly from Open Firmware.
