lib: add NO_GENERIC_PCI_IOPORT_MAP
Some architectures need to override the way IO port mapping is done on PCI devices. Supply a generic macro that calls ioport_map, and make it possible for architectures to override. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Acked-by: Arnd Bergmann <arnd@arndb.de>
