cpufreq/cppc: Set the frequency used for computing the capacity

commit 5477fa249b56c59c3baa1b237bf083cffa64c84a upstream.

Save the frequency associated to the performance that has been used when
initializing the capacity of CPUs.

Also, cppc cpufreq driver can register an artificial energy model. In such
case, it needs the frequency for this compute capacity.
