This would be a nice thing to do, because the PPC CPU is the
only remaining in-tree user of the .load_state_old migration
hook, so if we declared that we don't support migrating from
those old versions of QEMU (1.5 and earlier, I think) then we
could delete the .load_state_old and .minimum_version_id_old
handling completely.
