description:
Move initialization of the iomem extent struct from mac68k_set_io_offset()
to mac68k_init(), so that we're through frobbing the MMU in special ways
by the time we get there.  While it doesn't actually cause a problem with
the current structure of our initialization code, it probably would have
in the future.
