From: Chandrashekar Devegowda <chandrashekar.devegowda@xxxxxxxxx>
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
