Convert the Asahi Kasei AK5386 ADC binding from text format
to YAML schema.

Signed-off-by: Manish Baing <manishbaing2789@gmail.com>

Changes in v2:
- Added dai-common.yaml reference and #sound-dai-cells to support
  generic sound card DAI links.
- Changed additionalProperties to unevaluatedProperties: false.
- Restored legacy reset-gpio property as deprecated to maintain DT ABI
  backward compatibility.

-AK5386 Single-ended 24-Bit 192kHz delta-sigma ADC
-
-This device has no control interface.
-
-Required properties:
-
-  - compatible : "asahi-kasei,ak5386"
-
-Optional properties:
-
-  - reset-gpio : a GPIO spec for the reset/power down pin.
-		 If specified, it will be deasserted at probe time.
-  - va-supply : a regulator spec, providing 5.0V
-  - vd-supply : a regulator spec, providing 3.3V
-
-Example:
-
-spdif: ak5386@0 {
-	compatible = "asahi-kasei,ak5386";
-	reset-gpio = <&gpio0 23>;
-	va-supply = <&vdd_5v0_reg>;
-	vd-supply = <&vdd_3v3_reg>;
