[PATCH v2 08/29] clk: mediatek: clk-mtk: Add MUX_DIV_GATE macro

[Laura Nao <laura.nao@collabora.com>]

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.
