[POWERPC] Move pSeries_mach_cpu_die() into platforms/pseries/hotplug-cpu.c
Move pSeries_mach_cpu_die() into platforms/pseries/hotplug-cpu.c, this allows rtas_stop_self() to be static so remove the prototype. Wire up pSeries_mach_cpu_die() in the initcall, rather than statically in setup.c, the initcall will still run prior to the cpu hotplug code being callable, so there should be no change in behaviour.
