ASoC: mediatek: mt8188: 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.
