The driver creates a fake "ibmebus" device so all ibmebus based devices 
have
a common parent device -- the vio bus does the same.

What do you think about linking this device to the device tree "/" node? 
All
ibmebus-based devices are linked to dt nodes residing directly beneath 
"/",
so the mapping would fit.

Cheers,
