For easier handling of future processors using the POWER9 or something
close to it, add a new bit in the MMU model. This was originally from a
revised version of 86cf1e9 "target/ppc/POWER9: Add ISAv3.00 MMU definition"
but the older version of the patch was already merged. This makes the
change on top of the original version.
