We need to halt the APs on MP hibernate resume or else they will be
executing code possibly causing side effects during the image unpack
operation. But before we can halt the APs, we need to complete their init
(as they will be hatched but idling, possibly with interrupts off).
Introduces MD function hibernate_quiesce_cpus to do this, called from the
MI hibernate resume code.
