Colin Cross 1197ff38c1 cpuidle: coupled: fix sleeping while atomic in cpu notifier ...

The cpu hotplug notifier gets called in both atomic and non-atomic
contexts, it is not always safe to lock a mutex.  Filter out all events
except the six necessary ones, which are all sleepable, before taking
the mutex.
