ASoC: lpass-cpu: Move to yaml format

* Qualcomm Technologies LPASS CPU DAI

This node models the Qualcomm Technologies Low-Power Audio SubSystem (LPASS).

Required properties:

- 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-osr-clk"

				* "mi2s-bit-clk"

			: required clocks for "qcom,lpass-cpu-apq8016"

				* "ahbix-clk"

				* "mi2s-bit-clk0"

				* "mi2s-bit-clk1"

				* "mi2s-bit-clk2"

				* "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.

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

				* "lpass-irq-lpaif"

- pinctrl-N		: One property must exist for each entry in

			  pinctrl-names.  See ../pinctrl/pinctrl-bindings.txt

			  for details of the property values.

- pinctrl-names		: Must contain a "default" entry.

- reg			: Must contain an address for each entry in reg-names.

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

				* "lpass-lpaif"

- #address-cells	: Must be 1

- #size-cells		: Must be 0

Optional properties:

- qcom,adsp		: Phandle for the audio DSP node

By default, the driver uses up to 4 MI2S SD lines, for a total of 8 channels.

The SD lines to use can be configured by adding subnodes for each of the DAIs.

Required properties for each DAI (represented by a subnode):

- reg			: Must be one of the DAI IDs

			  (usually part of dt-bindings header)

- qcom,playback-sd-lines: List of serial data lines to use for playback

			  Each SD line should be represented by a number from 0-3.

- qcom,capture-sd-lines	: List of serial data lines to use for capture

			  Each SD line should be represented by a number from 0-3.

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.
