===========================================
Example 1 (ARM 64-bit, 6-cpu system, two clusters):
capacities-dmips-mhz are scaled w.r.t. 1024 (cpu@0 and cpu@1)
supposing cluster0@max-freq=1100 and custer1@max-freq=850,
final capacities are 1024 for cluster0 and 446 for cluster1
The capacities-dmips-mhz or DMIPS/MHz values (scaled to 1024)
are 1024 and 578 for cluster0 and cluster1. Further normalization
is done by the operating system based on cluster0@max-freq=1100 and
custer1@max-freq=850, final capacities are 1024 for cluster0 and
446 for cluster1 (576*850/1100).
