No, the drivers don't see any of this but instead someone has to
write (and maintain) explicit code to do the translation in arch/x86
outside the drivers. The drivers just see platform data and regular bus
probes which they'll be doing anyway until such time as device tree is
well enough established for people to stop doing platform data.
