ASoC: ak*: Remove now redundant non_legacy_dai_naming flag
The ASoC core has now been changed to default to the non-legacy DAI
naming, as such drivers using the new scheme no longer need to specify
the non_legacy_dai_naming flag.

ASoC: ak4458: Add DSD support for ak4458 and ak4497
Ak4458 can't support DSD512 format, but ak4497 can, so add
a new enum variable (enum ak4458_type) in ak4458_drvdata to
distinguish these two platforms.

Ak4497 has two kinds of DSD input pin, it can be selected by
the dsd-path property from DT.

In hw_params(), bit clock is calculated according to different
DSD format (DSD64, DSD128, DSD256, DSD512), then registers
are configured.

ASoC: ak4458: Add regulator support
"AVDD" is for analog power supply,  "DVDD" is for digital power
supply, they can improve the power management.

As the regulator is enabled in pm runtime resume, which is
behind the component driver probe, so accessing registers in
component driver probe will fail. Fix this issue by enabling
regcache_cache_only after pm_runtime_enable.

ASoC: codecs: ak*: merge .digital_mute() into .mute_stream()
snd_soc_dai_digital_mute() is internally using both
mute_stream() (1) or digital_mute() (2), but the difference between
these 2 are only handling direction.
We can merge digital_mute() into mute_stream

	int snd_soc_dai_digital_mute(xxx, int direction)
	{
		...
		else if (dai->driver->ops->mute_stream)
(1)			return dai->driver->ops->mute_stream(xxx, direction);
		else if (direction == SNDRV_PCM_STREAM_PLAYBACK &&
			 dai->driver->ops->digital_mute)
(2)			return dai->driver->ops->digital_mute(xxx);

ASoC: ak4458: Add support for AK4497
AK4497 is a 32-bit 2ch DAC and has the same register
map as AK4458 with few exceptions:

* AK4497 has one more register at the end of register space
  DFS_READ which is a read only register that allows users
  to read FS Auto Detection mode. We currently do not use
  this register so we use the same regmap structure as for ak4458.

* Because AK4458 is an 8ch DAC there are some fields that are
  only used by AK4458 and marked as reserved for AK4497, so for
  this reason we need to have a distinct set of controls, widgets
  and routes.

Datasheet for AK4497 is at:
https://www.akm.com/akm/en/file/ev-board-manual/AK4497EQ.pdf
