ASoC: Convert MT8183 DA7219 sound card to DT schema

Browse Source 
Convert the Device Tree binding for MT8183-based boards using the
DA7219 headset codec and optional MAX98357, RT1015 or RT1015P speaker
amplifiers from the legacy .txt format to DT schema.

This improves binding validation and removes DT schema warnings
for boards using these audio components.
