[PATCH 2/4] cpufreq: cpu0: Use clk_find_nearest_rate()

[Soren Brinkmann]

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.
