net/mlx4_core: Expose physical port id as PF/VF capability
Add the infrastructure needed to support ndo_get_phys_port_id which allows users to identify to which physical port a net-device is connected to by reading a unique port id. This will work for VFs and PFs. The driver uses a new device capability - phys_port_id, The PF driver reads the port phys_port_id from Firmware and stores it. The VF driver reads the port phys_port_id from the PF using QUERY_FUNC_CAP command.
