b277ad3bdb25e2fe7d53d470a57bf48edb6299df arch-arm: Only increment SW PMU counters on writes to PMSWINC
When writing a bitmask of counters to PMSWINC, the PMU currently
increments the corresponding counters regardless of what they are
configured to count. According to the ARM ARM (D5.10.4), counters
should only be updated if they have been configured to count
software events (event type 0).
