Current soc-pcm.c is coping fe hw_param to dpcm->hw_param (A),
fixup it (B), and copy it to be (C).

	int dpcm_be_dai_hw_params(...)
	{
		...
		for_each_dpcm_be(fe, stream, dpcm) {
			...
			/* copy params for each dpcm */
(A)			memcpy(&dpcm->hw_params, &fe->dpcm[stream].hw_params, ...) ;

			/* perform any hw_params fixups */
(B)			ret = snd_soc_link_be_hw_params_fixup(be, &dpcm->hw_params);
			...

			/* copy the fixed-up hw params for BE dai */
(C)			memcpy(&be->dpcm[stream].hw_params, &dpcm->hw_params, ...);
			...
		}
		...
	}

But here, (1) it is coping hw_params without caring stream (Playback/Capture),
(2) we can get same value from be. We don't need to have dpcm->hw_params.
This patch removes it.
