Bjoern A. Zeeb eeaf6acbfd Now that the PMU implementation is independent of HWPMC
as of r288992 use it to manage the CCNT.

Use the CNNT for get_cyclecount() instead of binuptime() when device pmu
is compiled in; if it fails to attach, fall back to the former method.

Enable by default for the BeagleBoneBlack configuration.
