[PATCH 1/2] ASoC: dt-bindings: renesas, rsnd: Clear warning 'dais' is a required property

[Zhen Lei <thunder.leizhen@huawei.com>]

When I do dt_binding_check, below warning is reported:
Documentation/devicetree/bindings/sound/renesas,rsnd.example.dt.yaml: \
sound@ec500000: 'dais' is a required property

I looked at all the dts files in the "arch/arm64/boot/dts/renesas/"
directory, I found that all nodes that contain the "dais" property have
compatible string: "audio-graph-card". So I can be sure that the
"$ref: audio-graph.yaml#" should be corrected to
"$ref: audio-graph-card.yaml#".

In addition, not all nodes have compatible string "audio-graph-card", so
the "$ref: audio-graph-card.yaml#" should be described as "anyOf". To
ensure the validation of "anyOf" always passes, group it with the "if"
statement, because the result of the "if" statement is always not empty.
