wcd_dsp_mgr: Add the WCD DSP manager driver

		asoc-codec-names = "msm-stub-codec.1";

		qcom,wsa-max-devs = <0>;

	};

* WCD DSP manager driver

Required properties:

- compatible : "qcom,wcd-dsp-mgr"

- qcom,wdsp-components : This is phandle list containing the references to the

			 components of the manager driver. Manager driver will

			 register to component framework with these phandles.

- qcom,img-filename : String property to provide the dsp image file name that is

		     to be read from file system and downloaded to dsp memory

Optional properties:

- qcom,wdsp-cmpnt-dev-name : Property that manager driver will parse, but defined

			     in the child's DT entry that is given to manager driver

			     with phandle. This property will be used by the manager

			     driver in case the manager driver cannot match child's

			     of_node pointer to registered phandle.

Example:

	qcom,wcd-dsp-mgr {

		compatible = "qcom,wcd-dsp-mgr";

		qcom,wdsp-components = <&wcd934x_cdc 0>,

				       <&wcd_spi_0 1>,

				       <&glink_spi 2>;

		qcom,img-filename = "cpe_9340";

	};

Example of child node that would have qcom,wdsp-cmpnt-dev-name property

	wcd934x_cdc: tavil_codec {

		qcom,wdsp-cmpnt-dev-name = "tavil_codec";

	};
