[Impact]

A Mediatek MT7922 Bluetooth doesn't work out of box.

[Fix]

One ID for Foxconn / Hon Hai was included in upstream, add the ID to support this BT device.

[Test Case]

With firmware from bug 1997200, this will bring up MT7922 Bluetooth.
Check BD address from output of `hciconfig`.

[Where problems could occur]

This brings up new devices that wasn't working. After being up and
running, we may face some other runtime issue, e.g. power consumption.
