In cpu_ppc_set_papr() the UPRT and GTSE bits of the LPCR default value are
initialized based on on ppc64_radix_guest(). Which seems reasonable,
except that ppc64_radix_guest() is based on spapr->patb_entry which is
only set up in spapr_machine_reset, called _after_ cpu_ppc_set_papr() for
boot cpus. Well, and the fact that modifying the SPR default value for an
instance rather than a class is kind of yucky.
The initialization here is really only necessary or valid for
hotplugged cpus; the base cpu initialization already sets a value
that's good enough for the boot cpus until the guest uses an hcall to
configure it's preferred MMU mode.
So, move this initialization to the rtas_start_cpu() path, at which point
ppc64_radix_guest() will have a sensible value, to make sure secondary cpus
come up in an MMU mode matching the existing cpus.
