ASoC: tas2770: Convert tas2770 binding to yaml



Convert the tas2770 binding to yaml format.
Add in the reset-gpio to the binding as it is in the code but not
documented in the binding.

Texas Instruments TAS2770 Smart PA

The TAS2770 is a mono, digital input Class-D audio amplifier optimized for
efficiently driving high peak power into small loudspeakers.
Integrated speaker voltage and current sense provides for
real time monitoring of loudspeaker behavior.

Required properties:

 - compatible:	   - Should contain "ti,tas2770".
 - reg:		       - The i2c address. Should contain <0x4c>, <0x4d>,<0x4e>, or <0x4f>.
 - #address-cells  - Should be <1>.
 - #size-cells     - Should be <0>.
 - ti,asi-format:  - Sets TDM RX capture edge. 0->Rising; 1->Falling.
 - ti,imon-slot-no:- TDM TX current sense time slot.
 - ti,vmon-slot-no:- TDM TX voltage sense time slot.

Optional properties:

- interrupt-parent: the phandle to the interrupt controller which provides
                     the interrupt.
- interrupts: interrupt specification for data-ready.

Examples:

    tas2770@4c {
                compatible = "ti,tas2770";
                reg = <0x4c>;
                #address-cells = <1>;
                #size-cells = <0>;
                interrupt-parent = <&msm_gpio>;
                interrupts = <97 0>;
                ti,asi-format = <0>;
                ti,imon-slot-no = <0>;
                ti,vmon-slot-no = <2>;
        };
