Subject: [PATCH v2 1/3] Bluetooth: btusb: add QCA6174A compatible properties

We may need to specify a GPIO wake pin for this device, so add a
compatible property for it.

There are at least to USB PID/VID variations of this chip: one with a
Lite-On ID and one with an Atheros ID.

 * drop leading zeroes from VID, per documented binding
