s390x/kvm: pass values instead of pointers to kvm_s390_set_clock_*()
We are going to factor out the TOD into a separate device and use const
pointers for device class functions where possible. We are passing right
now ordinary pointers that should never be touched when setting the TOD.
Let's just pass the values directly.
Note that s390_set_clock() will be removed in a follow-on patch and
therefore its calling convention is not changed.
