rsrc-card is DPCM supported version of simple-card. Thus it has similar DT format. OTOH, snd_soc_dai_link requests cpu/codec, but one of them will be snd-soc-dummy in DPCM case, and DPCM requests frontend/backend dai_link. This means it might have multi backend/codec. And, SND_SOC_DAIFMT_xxx is based on "codec". Because of these difference, current rsrc card can't detect correct dai_fmt. This patch detect correct dai fmt from 1st "codec".
