ASoC: mediatek: mt8188: DPCM used FE and BE merged parameters 

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.
