Subject: [PATCH v3 2/2] ASoC: dt-bindings: renesas, rsnd: Clear warning 'ports' does not match any of the regexes

Currently, if there are more than two ports, or if there is only one port
but other properties(such as "#address-cells") is required, these ports
are placed under the "ports" node. So add the schema of property "ports".

Otherwise, warnings similar to the following will be reported:
arch/arm64/boot/dts/renesas/r8a774a1-beacon-rzg2m-kit.dt.yaml: \
sound@...00000: 'ports' does not match any of the regexes: \
'^rcar_sound,ctu$', '^rcar_sound,dai$', '^rcar_sound,dvc$', ...

A given binding should just use 'ports' or 'port' depending on it's need.
Both are not allowed at the same time. The check is done in "allOf".
