Mark Chen fc342c4dc4 Bluetooth: btusb: Add protocol support for MediaTek MT7921U USB devices 
There is mt7921 firmware download mechanism

1. Read Chip id from MT7921.

2. Download firmware by endpoint 0, it's the same mechanism with
mt7663/mt7668.
   (it's medaitek specific header format for downloading firmware.)

3. Enabling Bluetooth function.

The information in /sys/kernel/debug/usb/devices about the MT7921U
Bluetooth device is listed as the below.
