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.

Remove .owner field if calls are used which set it automatically

The PWR_DWN is Bit 7, so current code does not set the PWR_DWN bit. Fix it.

The struct cs4349_platform_data should be defined in a public header in
include/sound/ rather than in sound/soc/codecs folder.
In additional, the platform data support is not properly handled in this
driver so remove it now.

The first valid register index is 1 rather than 0, and the CS4349_CHIPID
is readonly. So set .writeable_reg to avoid writing to these registers.

rtd->codec does not necessarily point to the CODEC instance for which the
callback was called (e.g. for CODEC<->CODEC or multi-CODEC links). Use
dai->codec instead.

dev_get_drvdata() will not return the snd_soc_runtime to which this CODEC
is attached, so the current code will result in undefined behavior.
To fix this just use regmap_update_bits(cs4349->regmap, ...) directly
instead of snd_soc_update_bits(rtd->codec, ...).
