Some devices (BCM4749, BCM5357, BCM53572) have internal switch that requires initialization. We already have code for this, but because of the typo in code it was never working. This resulted in network not working for some routers and possibility of soft-bricking them. Use correct bit for switch initialization and fix typo in the define.
