cpufreq: sh: Don't validate the frequency table twice
The cpufreq core is already validating the CPU frequency table after
calling the ->init() callback of the cpufreq drivers and the drivers
don't need to do the same anymore. Though they need to set the
policy->freq_table field directly from the ->init() callback now.
Stop validating the frequency table from sh-cpufreq driver.
The driver though prints the min/max frequency values and the same is
done from the ->ready() callback now to keep the behavior unchanged.
