ASoC: mediatek: mt8186: Migrate to mtk_soundcard_common_probe
Add mtk_soundcard_pdata platform data for the MediaTek common sound card probe mechanism, including a driver/soc-specific probe extension (used for bits that cannot be commonized hence specific to this driver), and change the probe function to mtk_soundcard_common_probe. This is also adding the possibility of specifying the links and routing with the audio-routing property and (x)-dai-link nodes in device trees to stop hardcoding machine specific links in the card driver assupported by the common probe function, but support for legacy device trees is retained with a legacy_probe function, which is used only in case the new properties are not found.
