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 for the new s390-ccw-virtio-5.0 machine now.
While at it, also add a more verbose comment why we need the *_allowed()
wrappers in s390-virtio-ccw.c.
