ASoC: tas6424: Allow disabling auto diagnostics for faster power-on The TAS6424 incorporates both DC-load and AC-load diagnostics which are used to determine the status of the load. The DC diagnostics runs when any channel is directed to leave the Hi-Z state and enter the MUTE or PLAY state. The DC diagnostics are turned on by default but, if a fast startup without diagnostics is required, the diagnostics can be disabled using a dedicated ALSA control.
