Lots of stuff (like the MFD children of I2C devices) gets shoved on the
platform bus on Linux - every time someone considers creating a new bus
type for trivial devices the discussion ends up saying that the code
will end up being pretty much identical to the platform bus as it's so
straightforward so there's no point in cut'n'pasting the code.

There's a general idea to kill of the system devices as the fact that
they do special magic and don't have things like a struct device creates
integration problems.
