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.

ASoC: tas6424: Add support for TAS6424 digital amplifier
The Texas Instruments TAS6424 device is a high-efficiency quad-channel
Class-D audio power amplifier. Its digital time division multiplexed
(TDM) interface enables up to 2 devices to share the same bus,
supporting a total of eight channels from one audio serial port.
