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.
