Declare `snd_soc_component_driver` as const to move it to a read-only
section for the drivers that do not modify the struct after its
declaration.
The affected drivers only pass this struct to
`devm_snd_soc_register_component()`, whose argument is const and
therefore does not modify the content of the struct.

IEC958-3 defines sampling rate up to 768 kHz.
Such rates maybe used with high bandwidth IEC958 links, such as eARC.

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.

AIO on UniPhier can output S/PDIF where no codec is needed.
This patch adds S32_LE support for dummy codec drivers.
If one S/PDIF controller has its own limitation, its CPU DAI driver should
set the supported format by its own circumstance, since the soc-pcm driver
will use the intersection of cpu_dai's formats and codec_dai's formats.

Declare snd_soc_codec_driver structures as const as they are only passed
as an argument to the function snd_soc_register_codec. This argument is
of type const, so declare the structures with this property as const.
In file codecs/sn95031.c, snd_soc_codec_driver structure is also used in
a copy operation along with getting passed to snd_soc_register_codec.
So, it can be made const too.

codec driver and component driver has duplicated callback functions,
and codec side functions are just copied to component side when
register timing. This was quick-hack, but no longer needed.
This patch moves these functions from codec driver to component driver.

Generally, S/PDIF supports 20bit and optional 24bit samples. Thus add these
two formats for the dummy codec drivers.
If one S/PDIF controller has its own limitation, its CPU DAI driver should
set the supported format by its own circumstance, since the soc-pcm driver
will use the intersection of cpu_dai's formats and codec_dai's formats.
