Subject: [PATCH v3 1/7] ASoC: mediatek: mt8188: separate ADDA playback dai from capture dai
MT8188 will support SOF. In SOF, be_hw_params_fixup callback are used to
configure BE hardware parameters. However, playback and capture stream
share the same callback function in which it can't know the stream type.
It's possible to require different parameters for playback and capture
stream, so separate them into two dais for SOF usage.
