dt-bindings: es8328: convert to DT schema format

Convert the binding to DT schema format. Note, that "IPVDD-supply"
got fixed to be "HPVDD-supply" during the conversion. This was
obviously a typo in the old binding. The old binding example, DT
files, chip datasheet and Linux driver use HPVDD.

-Everest ES8328 audio CODEC
-
-This device supports both I2C and SPI.
-
-Required properties:
-
-  - compatible  : Should be "everest,es8328" or "everest,es8388"
-  - DVDD-supply : Regulator providing digital core supply voltage 1.8 - 3.6V
-  - AVDD-supply : Regulator providing analog supply voltage 3.3V
-  - PVDD-supply : Regulator providing digital IO supply voltage 1.8 - 3.6V
-  - IPVDD-supply : Regulator providing analog output voltage 3.3V
-  - clocks : A 22.5792 or 11.2896 MHz clock
-  - reg : the I2C address of the device for I2C, the chip select number for SPI
-
-Pins on the device (for linking into audio routes):
-
-  * LOUT1
-  * LOUT2
-  * ROUT1
-  * ROUT2
-  * LINPUT1
-  * RINPUT1
-  * LINPUT2
-  * RINPUT2
-  * Mic Bias

-Example:
-
-codec: es8328@11 {
-	compatible = "everest,es8328";
-	DVDD-supply = <&reg_3p3v>;
-	AVDD-supply = <&reg_3p3v>;
-	PVDD-supply = <&reg_3p3v>;
-	HPVDD-supply = <&reg_3p3v>;
-	clocks = <&clks 169>;
-	reg = <0x11>;
-};
