clk: mediatek: Implement mtk_clk_unregister_factors() API

mtk_clk_register_factors(), as the name suggests, is used to register
a given list of fixed factor clks. However it is lacking a counterpart
unregister API.

Implement said unregister API so that the various clock platform drivers
can utilize it to do proper unregistration, cleanup and removal.

In the header file, the register function's declaration is also
reformatted to fit code style guidelines.
