The PTT trace collects PCIe TLP headers from the PCIe link and don't have the ability to exclude certain context. It doesn't support itrace as well. So replace PERF_PMU_CAP_ITRACE with PERF_PMU_CAP_NO_EXCLUDE. This will greatly save the storage of final data. Tested tracing idle link for ~15s, without this patch we'll collect ~28.682MB data for additional information and with this patch it reduced to ~0.226MB.
