Here ASoC doesn't need to know about sdw bus. As Srini explained, this
helps in the case for him to get the stream context and set the stream
context from the machine driver.

Nothing else is expected to be done from this API. We already do a set
using snd_soc_dai_set_sdw_stream(). Here we add the snd_soc_dai_get_sdw_stream() to query
