hwtracing: hisi_ptt: Advertise PERF_PMU_CAP_NO_EXCLUDE for PTT PMU
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.
