Subject: [PATCH v2 16/20] sparc: perf/core: advertise PMU exclusion capability

The SPARC 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.
