Thanks once again for your input and time!

I'll prepare patches for both issues. My guess is haswell-pcm could be
updated to handle 'platform' component param just fine, but it is
probably a change of more than few lines. I'd rather revert non-SOF
broadwell to its previous behavior and start a separate task from there.
