Subject: [PATCH 1/2] sched/cpufreq: Reorganize the cpufreq files

It was suggested to set the scene for the PM components in the
scheduler code organization in the recent discussion about making the
scheduler aware of the capacity capping from the thermal framework.

Move the cpufreq files into its own directory as suggested at:

https://lkml.org/lkml/2018/10/18/353
https://lkml.org/lkml/2018/10/18/408
