There are two ways we can load CPU capacity. Up until 4.14, supported kernels did not have the /sys/devices/system/cpu/cpuX/cpu_capacity file and the only way to read cpu capacity was by grepping the EM from procfs sched_domain output. After 4.14, that route still exists but is complicated due to a change in the format once support for frequency-power models was merged. In order to avoid rewriting the procfs EM grepping code, lets switch the order of algorithms we try to use when loading CPU capacity. All newer kernels provide the dedicated sysfs node and all kernels which do not have this node use the old format for the EM in sched_domain output.
