+CPU capacity is a number that provides the scheduler information about CPUs

+(e.g., ARM big.LITTLE systems) or maximum frequency at which CPUs can run
+(e.g., SMP systems with multiple frequency domains). Heterogeneity in this

Any reason why this capacity number is not dynamically generated based on the
max frequency for each CPU? The DT property would then instead specify just
the micro-architectural differences between the CPU types.
