[kvm-unit-tests,0/5] s390x: Add base AP support

As KVM supports passing Adjunct Processor (AP) crypto devices to
guests, we should make sure that the interface works as expected.

Three instructions provide the interface to the AP devices:
 - nqap: Enqueues a crypto request
 - dqap: Dequeues a crypto request
 - pqap: Provides information and processes support functions

nqap & dqap work on crypto requests for which we currently don't want
to add tests due to their complexity.

Which leaves us with pqap which is partly emulated for a guest 2 and
hence is a prime target for testing.
