DRA74x and DRA72x family of processors vary slightly in the number of CPUs. So, add different instances of PMU for each of these processor groups. Further, since the interrupts bypass crossbar and are directly connected to GIC, mark the dts nodes with relevant information. Tested with perf utility.
