ASoC: mediatek: mt8188: Constrain UL8 FE to its back end's capabilities
UL8 advertises up to 24 channels, but its only back end, ETDM1_IN,
supports at most 16, and its bit clock is limited to 24.576 MHz.
Without merged constraints, userspace can open UL8 with 48 kHz, 24
channels and 32-bit slots, which then fails in hw_params:
mtk_dai_etdm_configure bck rate 36864000 not support
ASoC error (-22): at snd_soc_dai_hw_params() on ETDM1_IN
Set dpcm_merged_chan/rate/format, as the DL front ends already do, so
the FE only offers configurations the back end can accept.
