ASoC: codecs: Add msm8916-wcd digital codec 



msm8916-wcd codec is found in Qualcomm msm8916 and apq8016 processors.
This codec IP is split in to two parts(Digital & Analog).
Analog part is integrated in to PMIC PM8916 and the digital part is
integrated into Application processor. Data transfer between Analog and
Digital Die is done via a internal bus called PDM.

This patch adds support to Digital part of the Codec which is integrated
into Application Processor.

## Bindings for codec core in lpass:



Required properties

 - compatible = "qcom,msm8916-wcd-digital-codec";

 - reg: address space for lpass codec.

 - clocks: Handle to mclk and ahbclk

 - clock-names: should be "mclk", "ahbix-clk".



Example:



audio-codec@771c000{

	compatible = "qcom,msm8916-wcd-digital-codec";

	reg = <0x0771c000 0x400>;

	clocks = <&gcc GCC_ULTAUDIO_AHBFABRIC_IXFABRIC_CLK>,

		 <&gcc GCC_CODEC_DIGCODEC_CLK>;

	clock-names = "ahbix-clk", "mclk";

	#sound-dai-cells = <1>;

};
