Hi Heiner

Ideally, we should do this to all the drivers, not just one. If we
leave PHY_HAS_INTERRUPT, people are going to use it. That then makes
the realtek driver then different to all the other drivers, and at
some point somebody will do something which breaks it because they
don't know the realtek driver is special.
