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

[Magnus Damm <magnus.damm@gmail.com>]

From: Magnus Damm <damm+renesas@opensource.se>

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.
