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>;
