Initial driver for PMU event counting on the Arm CMN-600 interconnect. CMN sports an obnoxiously complex distributed PMU system as part of its debug and trace features, which can do all manner of things like sampling, cross-triggering and generating CoreSight trace. This driver covers the PMU functionality, plus the relevant aspects of watchpoints for simply counting matching flits.
