Convert the AK4458 audio DAC bindings to DT schema.

Changes:
V1 -> V2: Use the correct way for dsd-path property
          Drop ak4458 label form example
V2 -> V3: ak4458 is the only one that does not support dsd-path, so we
          do not require to define an array

-AK4458 audio DAC
-
-This device supports I2C mode.
-
-Required properties:
-
-- compatible : "asahi-kasei,ak4458" or "asahi-kasei,ak4497"
-- reg : The I2C address of the device for I2C
-
-Optional properties:
-- reset-gpios: A GPIO specifier for the power down & reset pin
-- mute-gpios: A GPIO specifier for the soft mute pin
-- AVDD-supply: Analog power supply
-- DVDD-supply: Digital power supply
-- dsd-path: Select DSD input pins for ak4497
-            0: select #16, #17, #19 pins
-            1: select #3, #4, #5 pins
-
-Example:
-
-&i2c {
-	ak4458: dac@10 {
-		compatible = "asahi-kasei,ak4458";
-		reg = <0x10>;
-		reset-gpios = <&gpio1 10 GPIO_ACTIVE_LOW>
-		mute-gpios = <&gpio1 11 GPIO_ACTIVE_HIGH>
