* get_cpu_frequency - get the absolute value of frequency from level.

* @level: level of frequency, equals cooling state of cpu cooling device
* @level: cooling level

* This function matches cooling level with frequency. Based on a cooling level
* of frequency, equals cooling state of cpu cooling device, it will return

* e.g level=0 --> 1st MAX FREQ, level=1 ---> 2nd MAX FREQ, .... etc

* Return: 0 on error, the corresponding frequency otherwise.
