Looks to me that the devices created by of_platform_populate() are not
unregisterable in all cases. The address resource created via
of_platform_populate() had NULL res->parent, which causes
release_resource to crash.

I can as well call of_platform_populate() in the platform init code at
boot time, and create the devices there for now.
