dts: bindings: compatible properties are required

Any node which needs to generate defines from DTS must have a
"compatible" property, because the corresponding "constraint" is what
extract_dts_includes.py uses to match nodes with YAML files.

There are a few YAML files in the tree that list compatible as
"optional".  Fix them.
