ASoC: mediatek: mt8186: add SOF support on mt8186-mt6366-da7219-max98357

1. Add widgets, routes and dai-links required by SOF

2. Only when adsp phandle could be retrieved from DTS, the SOF related part
of machine driver is executed.

3. Support dai-links could be specified from DTS, so that
we can disable AP side hardware controls when DSP SOF controls the same
audio FE.
