Rob Herring 22a41e9a50 dt-bindings: Fix missing '/schemas' in $ref paths
Absolute paths in $ref should always begin with '/schemas'. The tools
mostly work with it omitted, but for correctness the path should be
everything except the hostname as that is taken from the schema's $id
value. This scheme is defined in the json-schema spec.
