snd_soc_dai_ops are not supposed to change at runtime. All functions
working with snd_soc_dai_ops provided by <sound/soc-dai.h> work with
const snd_soc_dai_ops. So mark the non-const structs as const.

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 array ni_div does not need to be in global scope and is not
modified, so make it static const.
Cleans up sparse warning:
"symbol 'ni_div' was not declared. Should it be static?"

The I2C core always reports a MODALIAS of the form i2c:<foo> even if the
device was registered via OF, this means that exporting the OF device ID
table device aliases in the module is not needed. But in order to change
how the core reports modaliases to user-space, it's better to export it.
While there, move the MODULE_DEVICE_TABLE(i2c, max9867_i2c_id) just next
to the I2C device table declaration, for consistency with other drivers.
Before this patch:
$ modinfo sound/soc/codecs/snd-soc-max9867.ko | grep alias
alias: i2c:max9867
After this patch:
$ modinfo sound/soc/codecs/snd-soc-max9867.ko | grep alias

TLV_DB_RANGE_HEAD macro was obsoleted by commit bf1d1c9b61 ("ALSA: tlv:
add DECLARE_TLV_DB_RANGE()").
This commit removes usage of the macro, with the obsoleting macro renamed
to SNDRV_CTL_TLVD_DECLARE_DB_RANGE().

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.
