bnxt_en: Add GRO logic for BCM5731X chips.
Add bnxt_gro_func_5731x() to handle GRO packets for this chip. The
completion structures used in the new chip have new data to help determine
the header offsets. The offsets can be off by 4 if the packet is an
internal loopback packet (e.g. from one VF to another VF). Some additional
logic is added to adjust the offsets if it is a loopback packet.
