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.

Signed-off-by: Alexander Stein alexander.stein@ew.tq-group.com --- There is no in-tree user for aic32x4-gpio-func, so I just converted the bindings to YAML and skipped introducing a dt-binding header for defining the constants.
