I don't have a example platform which would need it but as I can see there are
platforms which want to do this when CPUs goes down from disable_nonboot_cpus(),
I would be in favor to keep this option available for them as well..
They might want
to do this when last CPU of a policy goes down, they might be able to save some
power over there.
