ASoC: simple-card-utils: add asoc_simple_card_set_dailink_name()
Current simple-card is creating dai_link->name / dai_link->stream_name. These are based on CPU + Codec name, or "fe.CPU" or "be.Codec" if it was DPCM. This patch adds asoc_simple_card_set_dailink_name() and set dailink name as common method.
