In the past we have seen issues related to cpu hotplug which are
observed in certain rare case scenarios and not always easy to
investigate and debug [1]. Recently we merged a fix for specific cpu
hotplug scenario which observed along with kdump operations [2].

Additionally, spapr.c has grown to over 5000 lines which also contains
CPU hotplug related code which accounts for nearly 1000 of those lines
yet is conceptually self-contained and independent of the rest of the
machine model.

Extract the cpu hotplug related code into a new compilation unit,
spapr_cpu_hotplug.c, with a matching header.

Also, adding myself as reviewer for PPC KVM CPUs to help share the
review work.
