KVM: s390: Provide access to program parameter
commit d208c79d63e06457eef077af770d23dc4cde4d43 (KVM: s390: Enable
the LPP facility for guests) enabled the LPP instruction for guests.
We should expose the program parameter as a pseudo register for
migration/reset etc. Lets also reset this value on initial CPU
reset.
