This will replace the custom-made mlx5 ->add()/->remove() interfaces and next patches will fill the missing callback and remove the old interface logic. The attachment of auxiliary drivers to the devices is possible in 1-to-1 manner only and it requires us to create device for every protocol, so that device (module) will be able to connect to it.

It required to have both modules in initramfs if one of them needed for the boot.
