powerpc/pci: Move hose_list and pci_address_to_pio to pci-common
move the definition of hose_list next to its hotplug spinlock.
create pcibios_io_size to encapsulate ifdef in existing pci-common
function pcibios_vaddr_is_ioport
move pci_address_to_pio to pci-common, using new pcibios_io_size, and
protect this GPL exported function against concurrent hotplug removal
