This is an error since forever: the node is on an external bus and the
external bus while
defined in:
Documentation/devicetree/bindings/memory-controllers/intel,ixp4xx-expansion-bus-controller.yaml

Adds properties to any child, which can be any MMIO device.

I don't know what is the proper way to solve this.

A separate include .yaml for the children and then pull that into
every possible device on that bus?

OK I should write that yaml file.
