cpufreq: imx6q: Find max freq from frequency table itself
This is a preparatory commit to make policy->suspend_freq independent of validation of the cpufreq table, as a later commit would update cpufreq_generic_init() to not validate the cpufreq table any longer. The driver already assumes the order in which the frequency table is sorted and we can get the max frequency easily. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rafael J.
