[draft] ASoC: SOF: widget changing hw_params only applies to its sink widgets

[libinyang]

If a widget changes its output hw_params, the changed output hw_params should only applies to its sink widgets.

For example, we have 3 pipelines, ppl1, ppl2 and ppl3. And the topology is:

ppl1 --- ppl2
      |- ppl3

If we changed ppl2 hw_params, ppl3's hw_params should still use ppl1's output hw_params, instead of the ppl2's changed hw_params.

V2 update: move the memcpy into the loop.
