Juri Lelli 7673c8a4c7 sched/cpufreq: Remove arch_scale_freq_capacity()'s 'sd' parameter
The 'sd' parameter is never used in arch_scale_freq_capacity() (and it's hard to
see where information coming from scheduling domains might help doing
frequency invariance scaling).

Remove it; also in anticipation of moving arch_scale_freq_capacity()
outside CONFIG_SMP.
