clk: sunxi-ng: Add gate clock support Some clocks in the Allwinner SoCs clocks unit are just simple gates. Add support for those clocks. Since it's a feature that can also be found in more complex clocks, provide a bunch of helpers that can be reused later on.

clk: sunxi-ng: Add mux clock support Some clocks in the Allwinner SoCs clocks unit are just muxes. However, those muxes might also be found in some other complicated clocks that would benefit from the code in there to deal with "advanced" features, like pre-dividers. Introduce a set of helpers to reduce the code duplication in such cases.
