[PATCH RFC 02/13] of: add a dummy inline function for when CONFIG_OFis not defined

[Sylwester Nawrocki]

From: Guennadi Liakhovetski <g.liakhovetski@xxxxxx>

If CONFIG_OF isn't defined, no declaration of of_get_parent will be found
and compilation can fail. This patch adds a dummy inline function
definition to fix the problem.
