perf vendor events powerpc: Remove duplicate events
Some POWER PMU event names have multiple/alternate event codes. These alternate event codes were listed in the POWER9 JSON files for reference. But the perf tool does not seem to handle duplicates cleanly. 'perf list' shows such duplicate events only once, but 'perf stat' ends up counting the first event code twice, multiplexing if necessary and we end up with double the event counts. Remove the duplicate event codes from the JSON files for now.
