ASoC: sdw_utils: Remove asoc_sdw_find_codec_info_dai()

Remove the asoc_sdw_find_codec_info_dai() function because it
isn't reliable and is now unused.

It was finding the entry in codec_info_list[] by looking for the
matching DAI name. But this is not reliable because the DAI name
isn't guaranteed to be unique. Parts using the same codec driver
(so the same DAI names) might require different machine driver
setup.
