KVM: s390: SIE considerations for AP Queue virtualization 

The Crypto Control Block (CRYCB) is referenced by the SIE state
description and controls KVM guest access to the Adjunct
Processor (AP) adapters, usage domains and control domains.
This patch defines the AP control blocks to be used for
controlling guest access to the AP adapters and domains.
