+bgmac: fix internal switch initialization
+
+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.
