Move the calculation of a CPU's VCPU ID out of the generic PPC code
(ppc_cpu_realizefn()) and into sPAPR specific code
(spapr_cpu_core_realize()) where it belongs.
Unfortunately, due to the way things are ordered, we still need to
default the VCPU ID in ppc_cpu_realizfn() but at least doing that
doesn't require any interaction with sPAPR.
