Log Message:
In the __HAVE_NEW_PMAP_68K case, use machine_bootmap[] to map the I/O
area VA==PA.  With the Utah pmap, the I/O area was mapped at some
arbitrary KVA in pmap_bootstrap() and then double-mapped VA==PA in
mrg_init().  Initially, the new pmap case did this, as well, but then
mrg_init() blew up because no page tables were present for the address
it attempted to use.  Now that pmap_bootstrap1() ensures that PTs are
allocated for FIXEDVA entries in machine_bootmap[], we can just have
the one mapping.

Confirmed by nat@ that this makes mac68k boot and run with the new
pmap, but there are still gremlins when running the X server.
