[PATCH v3 2/3] perf tools: Sync perf_event_attr::config3 addition

From: Rob Herring
Date: Wed Sep 14 2022 - 16:09:44 EST


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.
