I fail to see how the different Linux behavior between drivers
built-in and as modules has anything whatsoever to do with DT. Fix the
problems in Linux and use the dependencies that are already expressed
in DT and *then* we can talk about using DT to provide *hints* for
solving any remaining problems.
