To ensure that DPCM takes into account the backend hardware limitations when user space queries the hw_params of a device, we need to add dpcm_merged_format, dpcm_merged_chan, and dpcm_merged_rate to the FE dai_links. This patch includes only stereo FE dai_links, since multi-channel FEs may be reserved for specific purposes. Therefore, it may not be appropriate to consider BE conditions.
