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.

As we can set the CODEC I/O while snd_soc_register_codec(), so the
calling of set_cache_io() from CODEC ASoC probe could be removed
entirely.
And then we can set the CODEC I/O in the device probe instead of
CODEC ASoC probe as earily as possible.

Now that all users have been converted to regmap and the config.reg_bits
and config.val_bits can be setted by each user through regmap core API.
So these two params are redundant here.
Since the only control type that left is SND_SOC_REGMAP, so remove it. Drop
the control params and add struct regmap *regmap to simplify the code.

The si476x is a MFD device and the CODEC driver is using the regmap struct of
the parent device, hence automatic IO setup will not work and we need to
manually call snd_soc_codec_set_cache_io(). The issue was introduced commit

The conversion of the si476x to regmap removed locking of the core during
register updates, allowing things like power state changes for the MFD to
happen during a register update. Avoid this by taking the core lock in the
DAI operations (which are the only things that do register updates) as we
used to do in the open coded register I/O functions.

The current si476x I/O implementation wraps the regmap for the core with
functions that make the register map cache only when the device is powered
down. This implementation appears to be incomplete since there is no code
to synchronise the cache so writes done while the core is powered down
will be ignored, the device will only be configured if it is powered.
A better and more idiomatic approach would be to have the MFD manage the
cache, making the device cache only when it powers things down. This also
allows ASoC to use the standard regmap helpers for the device which helps
remove the ASoC custom ones so do convert to do that.

This ensures the driver continues to work with DAPM mandatory and makes
it easier to connect the device up to other components in the subsystem.

The latest radio and MFD drivers for SI476X radio chips use regmap API
to provide access to the registers and allow for caching of their
values when the actual chip is powered off. Convert the codec driver
to do the same, so it would not loose the settings when the radio
driver powers the chip down.
