a0085f2510e8 ("Bluetooth: btusb: driver to enable the usb-wakeup feature")

feature"")
[Test]
Verified on machines which has paired BLE devices, and can't be waken up by BT
devices after entered suspended.
[Regression]
Yes, it reverts the feature by waking up system from BT devices, but this
feature introduces regression, so I'd suggest to revert it.
