Run dt-check-style as part of dt_binding_check_one. The recipe wraps the tool with scripts/jobserver-exec so worker count follows the GNU make jobserver -- `make -j N dt_binding_check` constrains the checker to N workers rather than spawning one per CPU. Default mode (relaxed) is zero-violation on the current tree, so this does not introduce new warnings into make dt_binding_check. Stricter rules are available via --mode=strict (eg. for use by checkpatch.pl in a future series).
