m2k: standalone: Set static switching activity for the reset signals 

The global reset signals are only asserted for a short moment during system
startup and deasserted during normal operation, which is the case we care
about for power analysis. Giving them a static switching probability
indicating that they are always de-asserted will yield better results for
power analysis.
