    linux-firmware: package MediaTek MT7925 Bluetooth firmware
    
    `btusb` fails to start on MT7925 hardware without the appropriate
    firmware being loaded first:
    ```
    bluetooth hci0: Direct firmware load for mediatek/mt7925/BT_RAM_CODE_MT7925_1_1_hdr.bin failed with error -2
    bluetooth hci0: Falling back to sysfs fallback for: mediatek/mt7925/BT_RAM_CODE_MT7925_1_1_hdr.bin
    ```
    Package firmware for MediaTek MT7925 Bluetooth from `linux-firmware`.
