Convert the mips architecture to make use of the new asm-generic/io.h to
provide address mapping functions. As mips actually performs
non-identity mapping between physical & virtual addresses we can't
simply make use of the generic functions, with the exception of being
able to drop our no-op unmap_physmem() and definitions of unused map
flags.
