Fix it as per review feedback. As per that feedback: - Subject should have been 'dt-bindings: phy:' which this patch now has. - We should leave no ambiguity in the ordering of 'reg' ranges even if 'reg-names' are also specified. - Normally using reg-names is discouraged unless there's a strong reason it's needed (like if there are optional ranges). In this case reg-names wasn't needed but the driver already landed relying on reg-names so we'll just document it and move on.
