of: Add two stubs for OF_ADDRESS=n and OF=n cases

[PATCH 01/02] of: Add OF_ADDRESS=n stub for of_can_translate_address() [PATCH 02/02] of: Add OF=n stub for of_find_all_nodes()

This series adds include file stubs for the following functions:
- of_can_translate_address() in of_address.h
- of_find_all_nodes() in of.h

With these stubs in place it is possible to remove Kconfig dependencies for OF and OF_ADDRESS in certain cases and just depend on the default behaviour of the stubs.

Written against renesas git repo at kernel.org using tag renesas-devel-v3.15-rc8-20140606 which for this code is the same as v3.15-rc8. Let me know if you want me to rebase.

Add a stub for the CONFIG_OF_ADDRESS=n case of of_translate_address(). The return value for the stub is false which is in sync with when the full version of the function does not support address translation. Added to allow removal of Kconfig dependency handling for CONFIG_OF_ADDRESS.

Add a stub for the CONFIG_OF=n case of of_find_all_nodes(). The return value for the stub is NULL which is in sync with when the full version of the function cannot find any nodes registered. Added to allow removal of Kconfig dependency handling for CONFIG_OF.
