Add a mechanism for mlx4 protocol drivers to get a pointer to other drivers's device objects. For this, an exported function, mlx4_get_protocol_dev() is added, which allows a driver to get some other driver's device based on the protocol that the driver implements. Two protocols are added: MLX4_PROTOCOL_IB and MLX4_PROTOCOL_EN. This will be used in mlx4 IBoE support so that mlx4_ib can find the corresponding mlx4_en netdev.
