Subject: [PATCH v2 13/20] powerpc: perf/core: advertise PMU exclusion capability

For PowerPC PMUs that have 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.
