Right now this function returns the current rate of the clock in the case when the round_rate() is not given in the clock's ops. This breaks clk_set_rate(), which calls clk_round_rate() to check if the resulting frequency would be the same as the one that is already set. Make it so that clk_round_rate() returns the frequency that was given as argument in this case.
