Use the run_wake flag to mark all devices for which run-time wake-up
events may be generated by the platform.  Introduce a new wake-up
flag, always_enabled, for marking devices that should be permanently
enabled to generate run-time events.  Also, introduce a reference
counter for run-wake devices and a function that will initialize all
of the run-time wake-up fields for given device.
