Now that all of the MT8135 clock drivers (including apmixedsys) can be compiled as modules, change the COMMON_CLK_MT8135 configuration option to tristate to enable module build. While at it, also remove the __initconst annotation from all of the clock arrays as they are not only used during init anymore, but also during runtime.
