[ARM] nommu: remove fault-armv, mmap and mm-armv files from nommu build

Remove fault-armv.o, mmap.o and mm-armv.o from uclinux builds - these
are concerned with MMU-ful operations, and as such are redundant for
uclinux.

Since this also removes iotable_init() and iotable_init() is used
extensively in the platform support files, just make it a no-op.

Based upon a couple of patches by Hyok.
