This fixed the issue for me where I had dependencies for QUP I2C driver and GHES
drivers. Both of them are modules and get probed via normal module execution path.

However, I'm open to improvements.  Do you have a better suggestion? I can try
to add some _DEP stuff if it is present, but I remember Linux doesn't like _DEP
stuff too much.
