ASoC: Add sc7180 lpass cpu node

Required properties:

- compatible		: "qcom,lpass-cpu" or "qcom,apq8016-lpass-cpu"

- compatible		: "qcom,lpass-cpu" or "qcom,apq8016-lpass-cpu" or

			  "qcom,sc7180-lpass-cpu"

- clocks		: Must contain an entry for each entry in clock-names.

- clock-names		: A list which must include the following entries:

				* "ahbix-clk"

				* "mi2s-bit-clk3"

				* "pcnoc-mport-clk"

				* "pcnoc-sway-clk"

			: required clocks for "qcom,lpass-cpu-sc7180"

				* "audio-core"

				* "mclk0"

				* "mi2s-bit-clk0"

				* "mi2s-bit-clk1"

				* "pcnoc-sway-clk"

				* "pcnoc-mport-clk"

- interrupts		: Must contain an entry for each entry in

			  interrupt-names.

Note that adding a subnode changes the default to "no lines configured",

so both playback and capture lines should be configured when a subnode is added.

Example:

Examples:

1)

lpass@28100000 {

	compatible = "qcom,lpass-cpu";

		qcom,playback-sd-lines = <0 1>;

	};

};

2)
