arch/powerpc/kernel/ibmebus.c is the only remaining user of the
of_bus_type support code for initializing the bus and registering
drivers.  All others have either been switched to the vanilla platform
bus or already have their own infrastructure.

This patch moves the functionality that ibmebus is using out of
drivers/of/{platform,device}.c and into ibmebus.c where it is actually
used.  Also renames the moved symbols from of_platform_* to
ibmebus_bus_* to reflect the actual usage.

This patch is part of moving all of the of_platform_bus_type users
over to the platform_bus_type.

The ibmebus is essentially the platform bus of the IBM Power Systems (a.k.a.
pSeries a.k.a. System p), I think it would make a lot of sense to convert
the two drivers (ehca and ehea) on this bus into platform drivers as well.

The original reason for this bus was to provide a different IOMMU for them
than what is used on the PCI devices. This should now be possible in simpler
ways.

Agreed.  Anybody want to volunteer to craft a patch?

In the mean time, do you have any problem with this patch?  (assuming
nobody is able to take on the task of converting those drivers
immediately).
