[PATCH/RFC,2/2] arm64: dts: renesas: ulcb-kf: Fix pcm3168a audio codec node

"make dtbs_check":

    arch/arm64/boot/dts/renesas/r8a77951-ulcb-kf.dtb: audio-codec@44: ports: 'mclk-fs' does not match any of the regexes: '^port@[0-9a-f]+$', 'pinctrl-[0-9]+'
	    From schema: Documentation/devicetree/bindings/sound/ti,pcm3168a.yaml
    arch/arm64/boot/dts/renesas/r8a77951-ulcb-kf.dtb: audio-codec@44: ports:port@0:endpoint: Unevaluated properties are not allowed ('clocks' was unexpected)
	    From schema: Documentation/devicetree/bindings/sound/ti,pcm3168a.yaml
    arch/arm64/boot/dts/renesas/r8a77951-ulcb-kf.dtb: audio-codec@44: ports:port@1:endpoint: Unevaluated properties are not allowed ('clocks' was unexpected)
	    From schema: Documentation/devicetree/bindings/sound/ti,pcm3168a.yaml

Fix this by:
  1. Moving the "mclk-fs" property to the endpoint nodes, where it
     belongs according to .../sound/audio-graph-port.yaml,
  2. Dropping the bogus "clocks" properties.

I'm not tested, but in my quick check,
we can use "mclk-fs" under "ports", and we need "clocks" under "endpoint".
So the issue is not dtsi side, but yaml side.

I will check and fix it, but it will be next week or later.

Thank you for your help !!

Best regards

I have investigated about this patch, and it needs extra patch
which I will post if -rc1 was released.
I can merge this patch (with small fixup) into my patch-set.
Of course I will keep your name. But is it OK for you ?

Thank you for your help !!
