      Add support for FEAT_MTPMU for Armv8.6 · 0063dd17

      If FEAT_PMUv3 is implemented and PMEVTYPER<n>(_EL0).MT bit is implemented
      as well, it is possible to control whether PMU counters take into account
      events happening on other threads.
      
      If FEAT_MTPMU is implemented, EL3 (or EL2) can override the MT bit
      leaving it to effective state of 0 regardless of any write to it.
      
      This patch introduces the DISABLE_MTPMU flag, which allows to diable
      multithread event count from EL3 (or EL2). The flag is disabled
      by default so the behavior is consistent with those architectures
      that do not implement FEAT_MTPMU.
