ASoC: SOF: Do not reset hw_params for streams that ignored suspend

Setting the prepared flag to false marks the streams for the
hw_params to be reset upon resuming. In the case of
the D0i3-compatible streams that ignored suspend to
keep the pipeline active in the DSP during suspend,
this should not be done.
