ASoC: define playback and capture streams in dummy codec
This patch adds a playback and capture streams to the dummy codec DAI
configuration. Most permissive set of sampling rates and formats is used.
This patch is needed for playback and capturing on a codec-less systems,
as otherwise the PCM device nodes are not even created.
