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

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.
