[PATCH 2/4] perf vendor events arm64: AmpereOne: Mark affected STALL_* events impacted by errata

[Ilkka Koskinen]

Per errata AC03_CPU_29, STALL_SLOT_FRONTEND, STALL_FRONTEND, and STALL
events are not counting as expected. The follow up metrics patch will
include correct way to calculate the impacted events.
