clk: mediatek: mt8135: Convert to simple probe and enable module build

Convert the MT8135 clock drivers to platform_driver using the common
simple probe mechanism; special note goes to the introduction of
dummy clocks with ID 0 (where 0 is the first entry of a clock array)
for each clock controller: this was necessary because of a mistake
in the bindings for all MT8135 clock controllers, where the first
clock has ID 1 (hence, array would start from element 1) instead of
zero.

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.
