ARM: CPU hotplug: move cpu_killed completion to core code
We always need to wait for the dying CPU to reach a safe state before taking it down, irrespective of the requirements of the platform. Move the completion code into the ARM SMP hotplug code rather than having each platform re-implement this. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
