ASoC: dpcm: symmetry constraint on FE substream
We should set BE symmetric constraint on FE substream. in case one BE is used by two FE1/FE2, the first BE runtime will use FE1's substream->runtime. hence the FE1's will be constrained by BE symmetry property. Though, second FE2 call dpcm_apply_symmetry, the be_substream->runtime == FE1's substream->runtime. The FE2's substream->runtime will not be constrained by BE's symmetry property.
