ASoC: mediatek: mt8188: revise ETDM control flow

Replace register controls in snd_soc_dai_ops with snd_soc_dapm_widgets.
startup, shutdown and trigger ops are removed, and create DAPM_SUPPLY
to handle mclk, clock gating and etdm enabling. Additionally, mclk setup
sequence is also updated because of new supply enabling sequence.
