Subject: [PATCH v5 1/2] perf tools: Sync perf_event_attr::config3 addition

Arm SPEv1.2 adds another 64-bits of event filtering control. As the
existing perf_event_attr::configN fields are all used up for SPE PMU, an
additional field is needed. Add a new 'config3' field.

Signed-off-by: Rob Herring <robh@...nel.org>
