audio-graph-scu-card.c is supporting "prefix" which is used to avoid DAI naming conflict when CPU/Codec matching. But, sound card might have multi sub-devices, and each codec might need each prefix.
Now, ASoC is supporting snd_soc_of_parse_node_prefix(), let's support it on audio-graph-scu-card, too. It is keeping existing DT style.
It can't support each codec's prefix if sound card had multi sub-devices without this patch.
