[PATCH v9 03/10] sched: remove frequency scaling from cpu_capacity

[Vincent Guittot]

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. arch_scale_freq_capacity will be
revisited for scaling load with the current frequency of the CPUs in a later
patch.
