[PATCH v2 11/20] drivers/perf: perf/core: advertise PMU exclusion capability

The arm_pse PMU has the capability to exclude events based on
context. Let's advertise that we support the PERF_PMU_CAP_EXCLUDE
capability to ensure that perf doesn't prevent us from handling
events where any exclusion flags are set.
