bgmac: fix internal switch initialization

commit 6a391e7bf26c04a6df5f77290e1146941d210d49 upstream.

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.
