Tony Krowiak 37940fb0b6 KVM: s390: device attrs to enable/disable AP interpretation
Introduces two new VM crypto device attributes (KVM_S390_VM_CRYPTO)
to enable or disable AP instruction interpretation from userspace
via the KVM_SET_DEVICE_ATTR ioctl:

* The KVM_S390_VM_CRYPTO_ENABLE_APIE attribute enables hardware
  interpretation of AP instructions executed on the guest.

* The KVM_S390_VM_CRYPTO_DISABLE_APIE attribute disables hardware
  interpretation of AP instructions executed on the guest. In this
  case the instructions will be intercepted and pass through to
  the guest.
