perf pmu: Use available core PMU for raw events
When it finds a matching PMU for a legacy event, it should look for
core PMUs. The raw events also refers to core events so it should be
handled similarly.
On x86, PERF_TYPE_RAW should match with the existing cpu PMU. But on
ARM, there's no PMU with the matching type so it'll pick the first core
PMU for it.
