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.

gcc -Wextra warns about an obvious but harmless typo in the
pcm1681_writeable_reg function, which has an extra 'register
keyword', and in pcm179x, which has a second copy of that
declaration:
sound/soc/codecs/pcm1681.c:76:42: error: 'register' is not at beginning of declaration [-Werror=old-style-declaration]
sound/soc/codecs/pcm179x.c:62:42: error: 'register' is not at beginning of declaration [-Werror=old-style-declaration]
For consistency with the rest of the file, I'm changing this from
'unsigned register' to 'unsigned int', which has the same meaning
but causes no warning.

The de-emphasis sampling rate selection is controlled by BIT[3:4] of
PCM1681_DEEMPH_CONTROL register. Do proper left shift to set it.

The correct values referred by a boolean control are
value.integer.value[], not value.enumerated.item[].
The former is long while the latter is int, so it's even incompatible
on 64bit architectures.

For CODEC controls snd_kcontrol_chip() currently returns a pointer to the
CODEC that registered the control. With the upcoming consolidation of
platform and CODEC controls this will change. Prepare for this by introducing
the snd_soc_kcontrol_codec() helper function that will hide the implementation
details of how the CODEC for a control can be obtained. This will allow us to
change this easily in the future.
The patch also updates all CODEC drivers to use the new helper function.
