sched/x86: Export 'percpu arch_freq_scale'

Browse Source 
Commit:

  7bc263840bc3 ("sched/topology: Consolidate and clean up access to a CPU's max compute capacity")

removed rq->cpu_capacity_orig in favor of using arch_scale_freq_capacity()
calls. Export the underlying percpu symbol on x86 so that external trace
point helper modules can be made to work again.
