Daniel Mack 385a4c2e28 ASoC: ak4104: add reset line property to DT bindings
This device doesn't have a pdata definition for legacy boards, and
unless anyone need to control the reset GPIO, it's not worth adding one.
So this feature is only available to DT users for now.

This device supports SPI mode only.
Required properties:
- compatible : "asahi-kasei,ak4104"
- reg : The chip select number on the SPI bus
Optional properties:
- reset-gpio : a GPIO spec for the reset pin. If specified, it will be
deasserted before communication to the device starts.
Example:
spdif: ak4104@0 {
compatible = "asahi-kasei,ak4104";
reg = <0>;
spi-max-frequency = <5000000>;
};
