Subject: [PATCH 1/2] PM / OPP: Use list_for_each_entry_reverse instead of
 list_for_each_entry

Most of the cpufreq table is sorted in descending order.
But when cpufreq table is made from dev_pm_opp_init_cpufreq_table,
it is sorted in ascending order. So in some case to make cpufreq table
with descending order it needs an extra work.
