H_VIOCTL is one of many VIO (Virtualized I/O) hcalls that we do not
support in QEMU. An AIX 7.2 guest will attempt to execute this hcall a
couple of times during boot, receiving H_FUNCTION replies every time,
and eventually give it up.
There are many VIO hcalls and we don't support none. H_VIOCTL seems to
be the one that convinces the guest that we don't have VIO support in
the platform, so let's add this one as unsupported in our model.
