phy: rockchip-usb: add missing of_node_put

for_each_available_child_of_node performs an of_node_get on each iteration,
so a return from the middle of the loop requires an of_node_put.

A simplified version of the semantic patch that finds this problem is as
follows (http://coccinelle.lip6.fr):

// <smpl>
@@
expression root,e;
local idexpression child;
@@

 for_each_available_child_of_node(root, child) {
   ... when != of_node_put(child)
       when != e = child
(
   return child;
|
*  return ...;
)
   ...
 }
// </smpl>
