clk: mediatek: clk-mtk: Introduce mtk_clk_get_hwv_regmap()
On MT8196, some clock controllers use a separate regmap for hardware
voting via set/clear/status registers. Add mtk_clk_get_hwv_regmap() to
retrieve this optional regmap, avoiding duplicated lookup code in
mtk_clk_register_muxes() and mtk_clk_register_gate().
