pinctrl: imx1-core: add missing of_node_put

Browse Source 
for_each_child_of_node performs an of_node_get on each iteration,
so of_node_put is required on break out of the loop.

This is done using Coccinelle. And semantic patch used for this is
as follows:

@@
expression root,e;
local idexpression child;
@@

 for_each_child_of_node(root, child) {
   ... when != of_node_put(child)
       when != e = child
(
   return child;
|
+  of_node_put(child);
?  return ...;
)
   ...
 }
