By design, of_platform_populate() will only go one level deep except
if it matches the passed in list of bus compatible properties. Having
a compatible property does not necessarily create a struct dev.

That said, I agree with you that a compatible property isn't really
needed in the child nodes **if it is defined as part of the parent
node's binding**.
