ASoC: dt-bindings: adi,adau7002: Convert to DT schema

Browse source 
Convert the Analog Devices ADAU7002 Stereo PDM-to-I2S/TDM Converter
bindings to DT schema.  During the conversion, add properties already
used by DTS (sc7180-trogdor-coachz.dts) and Linux driver:
1. wakeup-delay-ms,
2. sound-dai-cells (via referencing dai-common.yaml).

Required properties:
- compatible: Must be "adi,adau7002"
Optional properties:
- IOVDD-supply: Phandle and specifier for the power supply providing the IOVDD
supply as covered in Documentation/devicetree/bindings/regulator/regulator.txt
If this property is not present it is assumed that the supply pin is
hardwired to always on.

adau7002: pdm-to-i2s {
compatible = "adi,adau7002";
IOVDD-supply = <&supply>;
};
