ixgbe: Add FCoE feature code to 82599 



This adds the FCoE feature code ixgbe_fcoe.c to 82599. For a start, this patch
only adds ixgbe_configure_fcoe() to configure related register for FCoE to 82599.
In patches that follow, I will be adding more functions to ixgbe_fcoe.c to add
support of FCoE offload features to 82599.
