Recent series of patches targeting broadwell boards, while enabling SOF, changed behavior for non-SOF solutions. In essence replacing platform 'dummy' with actual 'platform' causes redundant stream initialization to occur during audio start. hw_params for haswell-pcm destroys initial stream right after its creation - only to recreate it again from proceed from there.
While harmless so far, this flow isn't right and should be corrected. The actual need for dummy components for SSP0 link is questionable but that issue is subject for another series.
