Convert the Asahi Kasei AK4118 S/PDIF transceiver bindings from
text format to YAML schema.

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

Changes in v2:
- Restored legacy 'irq-gpios' property to prevent C driver probe failure.
- Added 'reset-gpios' and 'irq-gpios' to the required properties list.

-This device supports I2C mode.
-
-Required properties:
-
-- compatible : "asahi-kasei,ak4118"
-- reg : The I2C address of the device for I2C
-- reset-gpios: A GPIO specifier for the reset pin
-- irq-gpios: A GPIO specifier for the IRQ pin

-Example:
-
-&i2c {

-		reset-gpios = <&gpio 0 GPIO_ACTIVE_LOW>
-		irq-gpios = <&gpio 1 GPIO_ACTIVE_HIGH>;
