Names must be generic and descriptive; this is the Bluetooth part of the MT7921s
hence it's called "bluetooth". If its functionality was "sdio", it'd be as such,
but this is BT anyway.

"sdio@xxx" would be applicable to, for example, a controller that provides support
exclusively for SDIO (with no support for eMMC/SD).
