KVM: s390: wire up bpb feature
[ Upstream commit 35b3fde6203b932b2b1a5b53b3d8808abc9c4f60 ]
The new firmware interfaces for branch prediction behaviour changes
are transparently available for the guest. Nevertheless, there is
new state attached that should be migrated and properly resetted.
Provide a mechanism for handling reset, migration and VSIE.
