Christian Borntraeger 572c082661 s390x: Add unpack facility feature to GA1 
The unpack facility is an indication that diagnose 308 subcodes 8-10
are available to the guest. That means, that the guest can put itself
into protected mode.

Once it is in protected mode, the hardware stops any attempt of VM
introspection by the hypervisor.

Some features are currently not supported in protected mode:
     * vfio devices
     * Migration
     * Huge page backings
