ASoC: dt-bindings: mediatek,mt8188-afe: add audio properties

Add apll1_d4 to clocks for switching the parent of top_a1sys_hp
dynamically and add property "mediatek,infracfg" for bus protection.

Because no mt8188 upstream dts exists, the change won't break anything.
In addition, apll2_d4, apll12_div4, top_a2sys and top_aud_iec are also
included in clocks, because these clocks are possibly used in the future.
