ASoC: mt8188: add new board support

Merge series from Trevor Wu <trevor.wu@mediatek.com>:

In the series, we extend the capability of mt8188-mt6359 driver.

The following changes are included.
1. Divide ADDA BE dai into two dais for SOF.
2. Register hdmi/dp jack pins.
3. dai_fmt can be configured from device tree.
4. Add some I2S codecs support.

In addition, new compatible string "mediatek,mt8188-nau8825" is
included for a new board support.
