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 Signed-off-by: Milton Miller <miltonm@bga.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
