ASoC: qdsp6: dt-bindings: Add q6afe dt bindings

Qualcomm Audio Front End (Q6AFE) binding

AFE is one of the APR audio service on Q6DSP

Please refer to qcom,apr.txt for details of the common apr service bindings

used by all apr services. Must contain the following properties.

- compatible:

	Usage: required

	Value type: <stringlist>

	Definition: must be "qcom,q6afe-v<MAJOR-NUMBER>.<MINOR-NUMBER>"

		  Or "qcom,q6afe" where the version number can be queried

		  from DSP.

		  example "qcom,q6afe"

= AFE DAIs (Digial Audio Interface)

"dais" subnode of the AFE node. It represents afe dais, each afe dai is a

subnode of "dais" representing board specific dai setup.

"dais" node should have following properties followed by dai children.

- #sound-dai-cells

	Usage: required

	Value type: <u32>

	Definition: Must be 1

- #address-cells

	Usage: required

	Value type: <u32>

	Definition: Must be 1

- #size-cells

	Usage: required

	Value type: <u32>

	Definition: Must be 0

== AFE DAI is subnode of "dais" and represent a dai, it includes board specific

configuration of each dai. Must contain the following properties.

- reg

	Usage: required

	Value type: <u32>

	Definition: Must be dai id

- qcom,sd-lines

	Usage: required for mi2s interface

	Value type: <prop-encoded-array>

	Definition: Must be list of serial data lines used by this dai.

	should be one or more of the 1-4 sd lines.
