perf/core, arch/powerpc: use PERF_PMU_CAP_NO_EXCLUDE for exclusion incapable PMUs
For PowerPC PMUs that do not support context exclusion let's
advertise the PERF_PMU_CAP_NO_EXCLUDE capability. This ensures that
perf will prevent us from handling events where any exclusion flags
are set. Let's also remove the now unnecessary check for exclusion
flags.
