clk: samsung: Extract clocks registration to common function

It might be useful to have a separate clocks registration function, so
it can be called from different users. Extract that common code from
samsung_cmu_register_one() to samsung_cmu_register_clocks(). Also make
that new function global as it's going to be used in other modules
further.
