Using snd_soc_card_get_codec_dai() might be a better choice throughout this
driver. While it will work for the cdn_dp case, because it is the first DAI
in |rockchip_dais[]|, all the invocations for the other codecs are likely
returning the wrong DAI.

For this particular patch it works either way, so
