ASoC: dt-bindings: Convert Allwinner A64 analog codec to a schema

The Allwinner A64 SoC has an embedded audio codec that uses a separate
controller to drive its analog part, which is supported in Linux, with a
matching Device Tree binding.

Now that we have the DT validation in place, let's convert the device tree
bindings for that controller over to a YAML schemas.

-* Allwinner A64 Codec Analog Controls
-
-Required properties:
-- compatible: must be one of the following compatibles:
-		- "allwinner,sun50i-a64-codec-analog"
-- reg: must contain the registers location and length
-- cpvdd-supply: Regulator supply for the headphone amplifier

-Example:
-	codec_analog: codec-analog@1f015c0 {
-		compatible = "allwinner,sun50i-a64-codec-analog";
-		reg = <0x01f015c0 0x4>;
