ASoC: dt-bindings: tlv320aic32x4: convert to DT schema format
Convert the binding to DT schema format.
Since commit 514b044cba667 ("ASoC: tlv320aic32x4: Model PLL in CCF")
clocks & clock-names = "mclk" is mandatory, it has been added to required
properties as well. '#sound-dai-cells' is added for reference from
simple-audio-card.
