That's a pretty odd case. Lots of devices can a crystal and this is not
how we describe it. I think the clock node should just be moved out of
this node to the top level to fix this.

Ideally, when the schema was converted, the warnings from it were looked
at and were either fixed in the schema on conversion (with notes in
commit msg) or the warnings were left as to be fixed in the .dts files.

BTW, dtbs_check is run on every schema patch for the schema in the
patch. Results are here[1].
