Pad iommu with an empty slot (necessary for SunOS 4.1.4)
On the real hardware (SS-5, LX) the MMU is not padded, but aliased.
Software shouldn't use aliased addresses, neither should it crash
when it uses (on the real hardware it wouldn't). Using empty_slot
instead of aliasing can help with debugging such accesses.
