Currently IO_SPACE_LIMIT is 0xffff, which is probably borrowed from the legacy
i386 code. Let us remove that limit, so that each machine does not have to
laboriously reset it.
BTW, a prudent machine port should probably always reset it to a more sane
range - in any case having 0xffff default value does not make much sense.
