On MT8196, some clocks use one register for parent selection and gating, and a separate register for frequency division. Since composite clocks can combine a mux, divider, and gate in a single entity, add a macro to simplify registration of such clocks by combining parent selection, frequency scaling, and enable control into one definition.
