ASoC: Add ADAU7002 Stereo PDM-to-I2S/TDM Converter DT bindings

The ADAU7002 takes a stereo PDM signal (e.g. from two digital microphones)
and converts it into a I2S/TDM PCM stream. The chip does not have a
control interface and has a single power supply that is modeled in the
devicetree.

Analog Devices ADAU7002 Stereo PDM-to-I2S/TDM Converter
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.
Example:
adau7002: pdm-to-i2s {
compatible = "adi,adau7002";
IOVDD-supply = <&supply>;
};
