'capacity_orig' is only changed for systems with an SMT sched_domain level in order to reflect the lower capacity of CPUs. Heterogenous systems also have to reflect an original capacity that is different from the default value. Create a more generic function arch_scale_cpu_capacity that can be also used by non SMT platforms to set capacity_orig. The __weak implementation of arch_scale_cpu_capacity() is the previous SMT variant, in order to keep backward compatibility with the use of capacity_orig. arch_scale_smt_capacity() and default_scale_smt_capacity() have been removed as they were not used elsewhere than in arch_scale_cpu_capacity().
