This allows the Bluetooth to communicate with the SystemSuspend to obtain system wakeup and wakelock information for Bluetooth activity attribution (BTAA) processing. BTAA is a process unit within the Bluetooth stack to aggregate Bluetooth traffics, wakeup, and wakelocks into per-app, per-device, and activity based statistical information. Test: Local test verified Bluetooth can acquire suspend_control Bug: 170315554 Change-Id: I7417132793c1000a8e3136c300cf8c1ba9cc3a14
