In the Power Library, a new bit has been added to the mask returned by
rte_power_get_capabilities which indicates whether the core is an
Intel SST-BF high frequency core.
The Distributor sample app has also been enhanced to make use of SST-BF
cores, and pin relevant workloads to the higher frequency cores, if
available in the core mask provided to the application.
