ASoC: tfa9879: Add device tree bindings 

Even though the tfa9879 driver can probe via device tree trough the
I2C core code, it is preferable to have explicit device tree
bindings instead [1], so add this support.

Required properties:



- compatible : "nxp,tfa9879"



- reg : the I2C address of the device



Example:



&i2c1 {

	clock-frequency = <100000>;

	pinctrl-names = "default";

	pinctrl-0 = <&pinctrl_i2c1>;

	status = "okay";



	codec: tfa9879@6c {

		#sound-dai-cells = <0>;

		compatible = "nxp,tfa9879";

		reg = <0x6c>;

        };

};
