PM: Add flag for devices capable of generating run-time wake-up events
Apparently, there are devices that can wake up the system from sleep states and yet are incapable of generating wake-up events at run time. Thus, introduce a flag indicating if given device is capable of generating run-time wake-up events. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
