KVM: s390: Provide access to program parameter

commit 5e02639c5610cc8187145651986f2f5bc385689d (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.
