A non-existing state may not be a problem if barebox state is unused.
An error message is printed in that case inside of_read_file and failing
the initcall results in a second error message, which is annoying.
Change this to only print an info message and move along.
of_unflatten_dtb() will report errors to parse the file on its own.
