Currently just add aliases for part of Arm CMN PMU events which are general and compatible for any SoC and CMN-ANY. "Compat" value "434*;436*;43c*;43a*" means it is compatible with all CMN600/CMN650/CMN700/Ci700, which can be obtained from commit 7819e05a0dce ("perf/arm-cmn: Revamp model detection").
