s390x: protvirt: Support unpack facility
The unpack facility provides the means to setup a protected guest. A
protected guest cannot be introspected by the hypervisor or any
user/administrator of the machine it is running on.
Protected guests are encrypted at rest and need a special boot
mechanism via diag308 subcode 8 and 10.
Code 8 sets the PV specific IPLB which is retained separately from
those set via code 5.
Code 10 is used to unpack the VM into protected memory, verify its
integrity and start it.
