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.
