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.

The master and slave modes don't share the same table for MCLK/LRCLK
ratios. The slaves mode has bigger ratios that allow to use BCLK that
matche sampling frequency of 192khz.
This commit enables this rate only for slave mode, i.e it does not
declare this frequency in sysclk_contraints, resulting to an error in
master mode (not supported CLK).

Currently most of the standard rates are supported by this driver.
Instead of defining each supported rate one by one, we use the SND macro
SNDRV_PCM_RATE_8000_48000. Also adds support for 88.2khz as the codec
supports it and the sys clocks are already supported.

In master mode, SCLK and LRCLK signals are generated by the CODEC when
any of the ADC/DAC are enabled. SCLK is derived from MCLK via a
programmable division set by BLK_DIV, LRCLK is derived from MCLK via
another programmable division set by ADCFsRatio/DACFsRatio.
In slave mode, SCLK and LRCLK signals are received as inputs and
supplied externally. LRCLK and SCLK must be synchronously derived from
MCLK with specific rates. The device can auto detect MCLK/LRCLK ratio
according to a predefined table. LRCLK/SCLK ratio is usually 64 (SCLK =
64 * LRCLK)
This commits adds support to let to device auto detect and decide which
ratio to use. The mclkdiv2 and BCLK_DIV ratio and put to zero.

Currently, the function that changes the DAI format only supports master
mode. Trying to use a slave mode exits the function with -EINVAL and
leave the codec misconfigured. This commits adds support for enabling
the slave mode.

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.

Although the ES8328 does support different rates for capture and
playback, only very limited combinations are supported (8kHz and 48kHz
or 8.0182kHz and 44.1kHz) with most rates required to be symmetric.
Instead of adding a lot of complexity for little gain, let's enforce
symmetric rates.

The ADCCONTROL4 and DACCONTROL1 registers are similar but not identical,
with the DACCONTROL1 having each field starting one bit higher than
ADCCONTROL4.
Instead of introducing a magic shift, add new constants for the values
in ADCCONTROL4 and use a second variable to setup the ADC.

This ensures that the clock is setup after its frequency has been set;
the existing code in set_dai_fmt may be called before the clock rate has
been set resulting in an incorrect configuration.

This is using completely the wrong mask and value when updating the
register. Since the correct values are already defined in the header,
switch to using a table with explicit constants rather than shifting the
array index.

Valid values for "deemph" are zero and one but we accidentally allow
negative values as well. It's harmless but it causes static checker

The correct values referred by a boolean control are

The former is long while the latter is int, so it's even incompatible
