Now that arch_scale_cpu_capacity has been introduced to scale the original
capacity, the arch_scale_freq_capacity is no longer used (it was
previously used by ARM arch). Remove arch_scale_freq_capacity from the
computation of cpu_capacity. The frequency invariance will be handled in the
load tracking and not in the CPU capacity. 

Just a note:

Yes, we are scaling the load tracking of each task to compensate for
frequency scaling. I think that is all fine. Later we will have to feed
the current frequency into the energy model as well to figure out if
putting more tasks on a cpu will/should cause the frequency to increase
or not. We don't need it for now and don't need to add it in the commit
message. It is just a reminder that we may actually want to use
arch_scale_freq_capacity() combined with cpu_capacity to provide this
input to the energy model later.
