ASoC: Add ssm2518 support 



This patch adds a ASoC CODEC driver for the SSM2516. The SSM2516 is a stereo
Class-D audio amplifier with an I2S interface for audio in and a built-in
dynamic range control processor.

SSM2518 audio amplifier



This device supports I2C only.



Required properties:

  - compatible : Must be "adi,ssm2518"

  - reg : the I2C address of the device. This will either be 0x34 (ADDR pin low)

	or 0x35 (ADDR pin high)



Optional properties:

  - gpios : GPIO connected to the nSD pin. If the property is not present it is

	        assumed that the nSD pin is hardwired to always on.



Example:



	ssm2518: ssm2518@34 {

		compatible = "adi,ssm2518";

		reg = <0x34>;

		gpios = <&gpio 5 0>;

	};
