The distributor sample application has been enhanced to be aware of
Intel SST-BF high frequency cores. Docs also contain a link to
the Intel SST-BF application note.

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.

Applied. Please try to update the release notes at the same time
as the code. Thanks

As part of the documentation update on the changes made to the power
library for 19.05, information on SST-BF was added. This patch updates
the comment to clarify that a priority core is an SST-BF high
frequency core.
