Subject: [PATCH v2 7/8] irda: sh_sir: Use cpufreq_for_each_valid_entry macro
 for iteration

The cpufreq core supports the cpufreq_for_each_valid_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.
