arm: wire frequency-invariant accounting support up to the task scheduler
Commit dfbca41f3479 ("sched: Optimize freq invariant accounting") changed the wiring which now has to be done by associating arch_scale_freq_capacity with the actual implementation provided by the architecture. Define arch_scale_freq_capacity to use the arch_topology "driver" function topology_get_freq_scale() for the task scheduler's frequency-invariant accounting instead of the default arch_scale_freq_capacity() in kernel/sched/sched.h.
