ARM: cns3xxx: Fix refcount leak in cns3xxx_init
commit 1ba904b6b16e08de5aed7c1349838d9cd0d178c5 upstream.
of_find_compatible_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.
Fixes: 415f59142d9d ("ARM: cns3xxx: initial DT support")
