Audio Graph endpoint is possible to have clock, but it is
missing its releated properties on audio-graph-port.
It is already defined on simple-card.
This patch adds it. Without this patch, we will get below warning
${LINUX}/arch/arm64/boot/dts/renesas/r8a77950-ulcb-kf.dtb: audio-codec@44: ports:port@0:endpoint: Unevaluated properties are not allowed ('clocks' was unexpected)
From schema: ${LINUX}/Documentation/devicetree/bindings/sound/ti,pcm3168a.yaml
