ASoC: Add bindings for PCM1789 

Add a device-tree binding for Texas Instrument's PCM1789 codec.
For the moment, only I2C bus is supported but SPI could be added
in future.

Texas Instruments pcm1789 DT bindings
PCM1789 is a simple audio codec that can be connected via
I2C or SPI. Currently, only I2C bus is supported.
Required properties:
- compatible: "ti,pcm1789"
Required properties on I2C:
- reg: the I2C address
- reset-gpios: GPIO to control the RESET pin
Examples:
audio-codec@4c {
compatible = "ti,pcm1789";
reg = <0x4c>;
reset-gpios = <&gpio2 14 GPIO_ACTIVE_LOW>;
#sound-dai-cells = <0>;
};
