dt: Add empty of_match_node() macro

Browse Source 
Add an empty macro for of_match_node() that will save
some '#ifdef CONFIG_OF' for non-dt builds.

I have chosen to use a macro instead of a function to
be able to avoid defining the first parameter.
In fact, this "struct of_device_id *" first parameter
is usualy not defined as well on non-dt builds.
