[PATCH v3 0/2] Add support for AK4458 DAC

[Cosmin-Gabriel Samoila <cosmin.samoila@nxp.com>]

We support Normal Mode, TDM Mode and PM.

Changes since V2:
- remove unused code left from V1
- rewrite set_dai_fmt to only remember the format since
- the format is rewritten in hw_params
- use defined constants for mode in set_tdm_slot function
- use GENMASK
- add commit message for bindings patch
- modify bindings description text since we only support I2C for now
- rename ak4458_codec_probe to ak4458_probe
- write whole implementation of regmap init and gpiod get in i2c_probe
- added ak4458_remove where we power_off the chip

Changes since V1:
- support only i2c
- i2c probe / remove/suspend/ resume moved into shared code                                                         
- change enum array to separate variables
- aggregate Volume control for Left and Right Channel
- remove mux from DAPM
- remove unused functions
- remove unused controls
- remove unused macros
- use snd_soc_update_bits instead of soc_read + soc_write
- use GPIOD
- use SPDX identifier
- use dac@10 instgitead of ak4458@10
- use explicit power_on/off functions
- add __maybe_unused attribute
- use probe_new for i2c_probe
