A stream is mapped to a converter. So based on the converters queried, dais are created.
The streams can be dynamically routed to any converter. For now it is mapped statically. The dynamic mapping of stream to converter will be added when required.

This is ugly... Can't we just set rate_min/max with the fixed numbers that cover the all possible ranges? The refinement is done by the rates bitmap and hw_constraint in anyway.
