Subject: [PATCH] ASoC: dt-bindings: Convert ti,tas2552 to DT schema

Convert the TI TAS2552 codec binding to DT schema format. It's a
straight-forward conversion.

-Texas Instruments - tas2552 Codec module
-
-The tas2552 serial control bus communicates through I2C protocols
-
-Required properties:
-	- compatible - One of:
-		"ti,tas2552" - TAS2552
-	- reg -  I2C slave address: it can be 0x40 if ADDR pin is 0
-				    or 0x41 if ADDR pin is 1.
-	- supply-*: Required supply regulators are:
-		"vbat"		battery voltage
-		"iovdd"		I/O Voltage
-		"avdd"		Analog DAC Voltage
-
-Optional properties:
-	- enable-gpio - gpio pin to enable/disable the device
-
-tas2552 can receive its reference clock via MCLK, BCLK, IVCLKIN pin or use the
-internal 1.8MHz. This CLKIN is used by the PLL. In addition to PLL, the PDM
-reference clock is also selectable: PLL, IVCLKIN, BCLK or MCLK.
-For system integration the dt-bindings/sound/tas2552.h header file provides
-defined values to select and configure the PLL and PDM reference clocks.
-
-Example:
-
-tas2552: tas2552@41 {
-	compatible = "ti,tas2552";
-	reg = <0x41>;
-	vbat-supply = <&reg_vbat>;
-	iovdd-supply = <&reg_iovdd>;
-	avdd-supply = <&reg_avdd>;
-	enable-gpio = <&gpio4 2 GPIO_ACTIVE_HIGH>;
-};
