ASoC: compress: Set reasonable compress id string

Commit Message

Donglin Peng Aug. 8, 2017, 2:59 a.m. UTC

For dynamic compress rtd, the codec_dai may not have any
actual meaning(like snd-soc-dummy-dai), so compress id
can just use the value of dai_link->stream_name. But for
others, its codec_dai has actual meaning, so compress id
can include codec_dai name.
