Perf: arm64: support hotplug and power collapse
Add notifiers for hotplug and power collapse in perf events.
Preserve counters and user enables across these events.
Disable and enable interrupts across events.
This allows perf-events to be used in an environment where
cores are power collapsing and being hotplugged.
