spapr: Clean up cpu realize/unrealize paths 

spapr_cpu_init() and spapr_cpu_destroy() are only called from the spapr
cpu core realize/unrealize paths, and really can only be called from there.

Those are all short functions, so fold the pairs together for simplicity.
While we're there rename some functions and change some parameter types
for brevity and clarity.
