While not documented, schema checks for single dtb targets mostly work
already by setting 'CHECK_DTBS=1'. However, the dependencies are not
handled and it only works if 'make dt_bindings_check' was run first and
generated processed-schema.json. In addition, changing a binding file
doesn't cause the schema to be rebuilt and dtb to be revalidated.
Making this work turns out to be simple. Whenever CHECK_DTBS is set,
make 'dt_binding_check' a 'dtbs_prepare' dependency.
I reimplemented here what Masahiro had originally come up with a while
back.
