Using a mask instead of the number of PMU devices supports the accurate emulation of platforms that have a discontinuous set of PMU counters. The "pmu-num" property now generates a warning when used by the user on the command line. Rather than storing the value for "pmu-num" convert it directly to the mask if it is specified (overwriting the default "pmu-mask" value) likewise the value is calculated from the mask if the property value is obtained. In the unusual situation that both "pmu-mask" and "pmu-num" are provided then then the order on the command line determines which takes precedence (later overwriting earlier.)
