dt-bindings: net: Fix unevaluatedProperties warnings in examples

The 'unevaluatedProperties' schema checks is not fully working and doesn't
catch some cases where there's a $ref to another schema. A fix is pending,
but results in new warnings in examples. Fix the warnings by removing
spurious properties or adding missing properties to the schema.
