[ARM] nommu: add stubs for ioremap and friends
nommu doesn't have any form of remapping support, so ioremap, etc become stubs which just return the casted address, doing nothing else. Move ioport_map(), ioport_unmap(), pci_iomap(), pci_iounmap() into a separate file which is always built. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
