Current audio-graph-card is handling "mclk-fs" by many way. But, it is not useful and readable. We want to do is that allow having mclk-fs everywere. This patch support it. It will be overwrote if lower node has it.
sound { mclk-fs = <xxx>; // initial };
codec { ports { mclk-fs = <xxx>; // overwrite port { mclk-fs = <xxx>; // overwrite endpoint { mclk-fs = <xxx>; // overwrite }; }; }; };
