sched/fair: Set asym priority equally for all CPUs in a performance domain

Browse Source 
All CPUs in a performance domain share the same capacity, and therefore
aren't different from one another when distinguishing between which one is
better for asymmetric packing.

Instead of unfairly prioritizing lower-numbered CPUs within the same
performance domain, treat all CPUs in a performance domain equally for
asymmetric packing.
