Right, like i2c bus we could just have platform core clean up platform

I2C doesn't do this (at least not any more).

Then individual drivers do not have to care about cleaning up this
pointer.

They don't have to worry about it anyway, the only thing that is allowed
to use the pointer is a currently bound driver and it's only allowed to
rely on is that while it's bound it'll get back the same driver_data
that it put in.
