ARM: versatile: support no-MMU mode addressing

Currently for the versatile boards the IO_ADDRESS() macro applies static
virtual address mapping for built-in IO devices. When operating without
the MMU enabled IO devices are accessed at their physical address, no
address translation is required.

For the !CONFIG_MMU case then define the IO_ADDRESS() macro to return the
physical address.
