Re: [PATCH 3/6] OF: Export all DT proc update functions

The 3rd patch is in preparation for some patches I have in WIP that would allow
drivers to set notifications for properties that are changed in runtime.
I think that since you have the all configuration taking place via DT and you
have a method to alter DT properties in run-time via /proc/device-tree, it's quite
straightforward to be able to alter runtime behavior via the same mechanism.
I.e. if you have some property that controls a devices behavior, it's intuitive that
when you modify that property, the device's state changes accordingly.
