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.
