memory: ti-aemif: Drop child node when jumping out loop
Call of_node_put() to decrement the reference count of the child node child_np when jumping out of the loop body of for_each_available_child_of_node(), which is a macro that increments and decrements the reference count of child node. If the loop is broken, the reference of the child node should be dropped manually.
