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 Analog part of the Codec which is integrated
into PMIC PM8916.

I will also add pmic into this compatible so that it will be clear that 
it is part of the PMIC chip.

something like "qcom,pm8916-wcd-analog-codec"

Ok, I will do that in next version.
