Commit ("d0565132605f perf evsel: Enable type checking for
perf_evsel_config_term types") assumes PERF_EVSEL__CONFIG_TERM_DRV_CFG
isn't used and as such adds a BUG_ON().

Since the enumeration type is used in macro ADD_CONFIG_TERM() the change
break CoreSight trace acquisition.

This patch restores the original code.
