[PATCH] cpufreq: cpufreq-cpu0: use the exact frequency for clk_set_rate()

[Guennadi Liakhovetski <g.liakhovetski@gmx.de>]

clk_set_rate() isn't supposed to accept approximate frequencies, instead
a supported frequency should be obtained from clk_round_rate() and then
used to set the clock.

Applies on top of my previous patch to fix unsigned freq_Hz "cpufreq: fix 
sign check of an unsigned variable in cpufreq-cpu0"
