Bluetooth: btusb: support public address configuration for ath3012
Set hdev->set_bdaddr handler for ath3012. It sends the vendor specific HCI command to change the public address. The change doesn't persist across power cycle. Signed-off-by: Toshi Kikuchi <toshik@chromium.org> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
