Yes, the of_find accessors etc. could be moved to their own file,
probably without too much pain.

The hotplug stuff (of_add_node, of_remove_node) necessarily uses the
same lock as the accessors, but we could take more care to avoid
building it on platforms which don't need it.  I believe those functions
should be compiled in only when building for pSeries with CONFIG_HOTPLUG=y.
