There is more than an "attempt". There is one and it works :-)

This is a compromise for legacy port (ok, it did grow a bit beyond
legacy stuff but still...) mostly to allow for very early initialisation
of serial ports.

Ultimately, if we generalize of_platform_devices for serial ports,
however, we will not need to create platform devices there anymore.
