[Impact]
Some QCA ROME bluetooth devices does not work after runtime suspended.

[Fix]
Latest mainline does not have this issue. The bisected commit is
a0085f2510e8976614ad8f766b209448b385492f "Bluetooth: btusb: driver to
enable the usb-wakeup feature".
With this commit, the BT device now can wake host controller up.

[Test]
Cherry-picked the commit into Artful/OEM kernel and the issue is fixed.

[Regression Potential]
Low. usb-wakeup support shouldn't affect the driver's function.
