ASoC: ssm2602: add device tree bindings 



Allow the ssm2602/ssm2603/ssm2604 codec driver to be
instantiated from the device tree.

Also, add Kconfig prompts to allow manual selection of both the
I2C and SPI configuration versions of the driver.

Analog Devices SSM2602, SSM2603 and SSM2604 I2S audio CODEC devices



SSM2602 support both I2C and SPI as the configuration interface,

the selection is made by the MODE strap-in pin.

SSM2603 and SSM2604 only support I2C as the configuration interface.



Required properties:



  - compatible : One of "adi,ssm2602", "adi,ssm2603" or "adi,ssm2604"



  - reg : the I2C address of the device for I2C, the chip select

          number for SPI.



 Example:



	ssm2602: ssm2602@1a {

		compatible = "adi,ssm2602";

		reg = <0x1a>;

	};
