ASoC: rt722-sdca: add FU06 Playback Switch for speaker mute control

Browse source

The rt722-sdca codec driver exposes FU06 Playback Volume but no
corresponding mute switch. Without a user-facing ALSA switch, UCM
cannot attach the speaker mute LED via snd_ctl_led, and PipeWire
cannot drive hardware mute.
