cpu_ppc_set_papr() sets up various aspects of CPU state for use with PAPR
paravirtualized guests.  However, it doesn't set the virtual hypervisor,
so callers must also call cpu_ppc_set_vhyp() so that PAPR hypercalls are
handled properly.  This is a bit silly, so fold setting the virtual
hypervisor into cpu_ppc_set_papr().
