Bug description:
[Impact]
Connected BLE devices like keyboard and mouse won't automatically
reconnect to host after system suspend.
[Fix]
New firmware from Realtek.
[Test]
With the new firmware used, BLE keyboard and mouse will reconnect to
host by pressing any key or by moving it.
[Where problems could occur]
Tried some other Bluetooth peripherals and didn't see any regression.
This is also internally tested by Realtek.
