Add compatible string "mediatek,mt8188-nau8825" to support new board with nau8825 codec. Introduce two properties "dai-format" and "mediatek,clk-provider" under dai-link subnode to configure dai-link parameters via dts. "codec" property is removed from required property of dai-link subnode. For co-clock case, it's possible two dai-links should be configured to the same dai format, but only one cpu dai is bound with codec.
