Subject: [PATCH 19/20] cpufreq: pcc_cbe: 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.
