[PATCH v5 6/8] thermal: cpu_cooling: Use cpufreq_for_each_valid_entry macro for iteration

[Stratos Karafotis <stratosk@semaphore.gr>]

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

Also remove the redundant !! operator.

It should have no functional changes.
