[SRU Justification]
[Impact]
Some Mediatek MT7921 Bluetooth doesn't work out of box.
[Fix]
One ID for Lite-On was included in upstream, but we need two additional
more from different vendors.
[Test Case]
With firmware from bug 1936452, this will bring up MT7921 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.
