The AIS feature has been disabled late in the v2.10 development cycle since
there were some issues with migration (see commit 3f2d07b3b01ea61126b -
"s390x/ais: for 2.10 stable: disable ais facility"). We originally wanted
to enable it again for newer machine types, but apparently we forgot to do
this so far. Let's do it now for the machines that support proper CPU models.

v5: Use cpu_model_allowed() as suggested by David. Seems to work as far
as I can test it without PCI cards, but ping-pong migration with
"-cpu host" from/to an older version of QEMU is now not working
anymore - but I think that's kind of expected since "-cpu host"
is not migration-safe anyway.
Ok, so I'll wait for test results with pci cards before queuing this :)
Ok, Matthew, could you please test one more time?
