ASoC: add TA5720 digital amplifier DT bindings

Browse source 
The Texas Instruments TAS5720L/M device is a high-efficiency mono
Class-D audio power amplifier optimized for high transient power
capability to use the dynamic power headroom of small loudspeakers.
Its digital time division multiplexed (TDM) interface enables up to
16 devices to share the same bus.

Texas Instruments TAS5720 Mono Audio amplifier
The TAS5720 serial control bus communicates through the I2C protocol only. The
serial bus is also used for periodic codec fault checking/reporting during
audio playback. For more product information please see the links below:
http://www.ti.com/product/TAS5720L
http://www.ti.com/product/TAS5720M
Required properties:
- compatible : "ti,tas5720"
- reg : I2C slave address
- dvdd-supply : phandle to a 3.3-V supply for the digital circuitry
- pvdd-supply : phandle to a supply used for the Class-D amp and the analog
Example:
tas5720: tas5720@6c {
status = "okay";
compatible = "ti,tas5720";
reg = <0x6c>;
dvdd-supply = <&vdd_3v3_reg>;
pvdd-supply = <&amp_supply_reg>;
};
