drivers/perf: hisi: Advertise the PERF_PMU_CAP_NO_EXCLUDE capability
Missed initialization the variable of pmu::capabilities when extract
the initialization code of hisi_pmu->pmu into a function.
HISI UNCORE PMU drivers counters that not support context exclusion.
So we have to advertise the PERF_PMU_CAP_NO_EXCLUDE capability.
This ensures that perf will prevent us from handling events where
any exclusion flags are set.
