Add the default regmap I/O setting to snd_soc_register_codec() while
the CODEC is initialising, which will be called by CODEC driver device

CODEC ASoC probe.

Nope. The driver struct is globally shared between all device instances, the
regmap struct is device instance specific. The proper way to solve this is
to have a function like snd_soc_register_codec_with_io() which takes a
pointer to the regmap struct.
