not an upstream compatible, please delete the node.

I think my comment was not correct. I'll have to dig more to understand why we
have a compatible without a binding description.

Here's a similar syscon node that is in a binding document's example:

syscfg_pctl_a: syscfg-pctl-a@10005000 {
        compatible = "mediatek,mt8135-pctl-a-syscfg", "syscon";
        reg = <0 0x10005000 0 0x1000>;
};

https://elixir.bootlin.com/linux/latest/source/Documentation/devicetree/bindings/pinctrl/pinctrl-mt65xx.txt#L81

Yes I know, that's why I said that my first comment was not correct. Just leave
it in.

Regards,
Matthias
