[PATCH v2 4/4] perf: Remove unused PERF_PMU_CAP_HETEROGENEOUS_CPUS capability

[James Clark]

Since commit bd2756811766 ("perf: Rewrite core context handling") the
relationship between perf_event_context and PMUs has changed so that
the error scenario that PERF_PMU_CAP_HETEROGENEOUS_CPUS originally
silenced no longer exists.

Remove the capability to avoid confusion that it actually influences
any perf core behavior and shift down the following capability bits to
fill in the unused space. This change should be a no-op.
