Subject: [PATCH 18/20] cpufreq: pasemi: Use cpufreq_for_each_entry macro for
 iteration

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.

Please note that I was no able to compile test this patch due to 
lack of cross compiler.
