Probably not a bad idea to follow pci here.

Yes, a control ccw sounds nice, we should just make sure that it
doesn't collide with future tests (e.g. if we want to do some channel
program fuzzing). Alternatively, this could be controled by a diagnose,
which would be out of band (we can use a high function code for diag
500 that is unlikely to collide with future extensions).
