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).
