powerpc/kexec: make the update_cpus_node() function public

Browse source

Move the update_cpus_node() from kexec/{file_load_64.c => core_64.c}
to allow other kexec components to use it.

Later in the series, this function is used for in-kernel updates
to the kdump image during CPU/memory hotplug or online/offline events for
both kexec_load and kexec_file_load syscalls.

No functional changes are intended.
