Add an iomap_name() function which translates an I/O map into a string to
print.
Use it for the Libata layer
For now we use 0xXXXX for I/O and 0xXXXXXXXX for MMIO. I'm assuming that
eventually some other platforms will want to use their own iomap_name() and
we can add ARCH_HAVE_IOMAP_NAME later as such a platform needs it.

this will truncate on 64-bit addresses
otherwise OK
