ASoC: soc-pcm: align BE 'atomicity' with that of the FE
Since the flow for DPCM is based on taking a lock for the FE first, we need to make sure during the connection between a BE and an FE that they both use the same 'atomicity', otherwise we may sleep in atomic context. If the FE is nonatomic, this patch forces the BE to be nonatomic as well. That should have no negative impact since the BE 'inherits' the FE properties. However, if the FE is atomic and the BE is not, then the configuration is flagged as invalid.
