Round clock frequencies to the nearest possible frequency. Since the OPPs as specified in DT and the CCF use different a resolution for clock frequencies, the clk_round_rate() API may return unexpected results, due to not mandating how rounding has to happen. The clk_find_nearest_rate() API mitigates such issues and finds the appropriate frequency for an OPP.
