[PATCH] ppc64: PCI cleanup

[PATCH] ppc64: PCI cleanup

- remove pci_fix_bus_sysdata. We required it for the old pci dma
  subsystem, but now it is useless.
- remove PCI_GET_PHB_PTR and use pci_bus_to_host instead
- remove pci_find_hose_for_OF_device
- remove some unused fields in struct pci_controller
- remove pci_device_loc stale prototype
- remove an old mask of pci bus number that was left around from the pre
  PCI domains days
