What is a goal of calling init_hwif_data() in ide_unregister()?
I guess it is used mainly to clear hwif->io_ports and hwif->irq.
Therefore even if you are using hwif->hold flag io_ports will be set to
default values, so how do you later find your hwif?
Hmmm... what about not copying anything and calling init_hwif_data()
only if !hwif->hold?
