[PATCH 16/20] mips: lemote 2f: se cpufreq_for_each_entry macro for iteration

From: Stratos Karafotis
Date: Mon Apr 14 2014 - 17:13:02 EST


The cpufreq core supports the cpufreq_for_each_entry macro helper
for iteration over the cpufreq_frequency_table, so use it.

It should have no functional changes.
