clk: sunxi: make factors clock mux mask configurable
Some of the factors-style clocks on the A80 have different widths for the mux values in the registers. Add a .muxmask field to clk_factors_config to make it configurable. Passing a bitmask instead of a width parameter will allow reuse in case we support table-based muxes in the future.
