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.

Still a call to spapr_cpu_reset(cpu). We should try to get rid of it
one day.

Yeah, CPU reset should ideally be triggered during machine reset or during
hotplug. There have been several tries to do so but we hit an issue with
hotplug... If we don't call spapr_cpu_reset() here then CPUState::halted
isn't set and the CPU can start executing before the hotplug path has a
chance to reset it...
