Yaniv Rosner 3971a230f9 bnx2x: Fix PHY locking problem 
PHY locking is required between two ports for some external PHYs. Since
initialization was done in the common init function (called only on the
first port initialization) rather than in the port init function, there
was in fact no PHY locking between the ports.
