Subject: [net-2.6 1/2] 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.
