clk: mediatek: cpumux: Propagate struct device where possible

Take a pointer to a struct device in mtk_clk_register_cpumuxes() and
propagate the same to mtk_clk_register_cpumux() => clk_hw_register().
Even though runtime pm is unlikely to be used with CPU muxes, this
helps with code consistency and possibly opens to commonization of
some mtk_clk_register_(x) functions.
