[ Upstream commit 3e94262921990e2884ff7a49064c12fb6d3a0733 ]
Implement hdev->wakeup() callback to support Wake On BT feature.
Test steps: 1. echo enabled > /sys/bus/pci/devices/0000:00:14.7/power/wakeup 2. connect bluetooth hid device 3. put the system to suspend - rtcwake -m mem -s 300 4. press any key on hid to wake up the system
