mlx4_core: Allow protocol drivers to find corresponding interfaces
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.
