[PATCH 0/3] Add generic idle notifiers

Add notifiers for idle entry and exit, called with IDLE_START when a
CPU goes idle and IDLE_END when it goes out of idle, based on the
existing idle notifiers for the x86_64 arch.

Convert x86_64 to use these notifiers, and call the notifiers on ARM.

Convert the ARM LEDs events for idle start/end to these notifiers.
