cpufreq: davinci: Reuse cpufreq_generic_frequency_table_verify()
policy->freq_table will always be valid for this platform, otherwise driver's probe() would fail. And so this routine will *always* return after calling cpufreq_frequency_table_verify(). This can be done using the generic callback provided by core, lets use it instead. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
