bnx2x, bnx2fc, bnx2i, cnic: Add statistics support and FCoE capabilities advertisement 

1. When FCoE offload driver is registered, copy its capabilities to the chip
   scratchpad.
2. Copy FCoE/iSCSI MAC addresses in aligned manner to chip scratchpad.
3. Add FCoE/iSCSI statistics collection support
