ASoC: msm: Add compress audio playback code base

Qualcomm technologies inc audio devices for ALSA sound SoC

* msm-compress-dsp

Required properties:

 - compatible : "qcom,msm-compress-dsp"

Optional properties

 - qcom,adsp-version:

	This property can be used to specify the ADSP version/name.

	Based on ADSP version, we decide if we have to use older

	ADSP APIs or newer. Right now we are adding "MDSP 1.2" for

	8909 purpose.If the ADSP version is anything other than this

	we use new ADSP APIs.

Example:

        qcom,msm-compress-dsp {

                compatible = "qcom,msm-compress-dsp";

        };
