Subject: [PATCH] of: base: Add of_get_next_child_with_prefix() stub

From: Bjorn Helgaas <bhelgaas@...gle.com>

1fcc67e3a354 ("of: base: Add for_each_child_of_node_with_prefix()") added
of_get_next_child_with_prefix() but did not add a stub for the !CONFIG_OF
case.

Add a of_get_next_child_with_prefix() stub so users of
for_each_child_of_node_with_prefix() can be built for compile testing even
when !CONFIG_OF.

Fixes: 1fcc67e3a354 ("of: base: Add for_each_child_of_node_with_prefix()")
