When there is no fault bit set in a fault register we skip the fault
reporting section for that register. This also skips over saving that
registers value. We save the value so we will not double report an
error, but if an error clears then returns we will also not report it
as we did not save the all cleared register value. Fix this by saving
the fault register value in the all clear path.

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.

mute can be connected to GPIO. In that case we have to drive it to the
correct value

The standby pin can be connected to a GPIO. In that case we have to drive
it to the correct values for the TAS6424 to operate properly.

Now we can replace Codec to Component. Let's do it.

Note:
	xxx_codec_xxx()		->	xxx_component_xxx()
	.idle_bias_off = 1	->	.idle_bias_on = 0
	.ignore_pmdown_time = 0	->	.use_pmdown_time = 1
	-			->	.endianness = 1
	-			->	.non_legacy_dai_naming = 1

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.
