Subject: PCI: Export symbols required for loadable host driver modules

Export the following symbols so they can be referenced by a PCI host bridge
driver compiled as a kernel loadable module:

  pci_common_swizzle
  pci_create_root_bus
  pci_stop_root_bus
  pci_remove_root_bus
  pci_assign_unassigned_bus_resources
  pci_fixup_irqs
