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.

6 - compatible = "qcom,msm8916-wcd-digital-codec";
7 - reg: address space for lpass codec.
8 - clocks: Handle to mclk and ahbclk
