power/reset: arm-versatile: Fix refcount leak in versatile_reboot_probe 



[ Upstream commit 80192eff64eee9b3bc0594a47381937b94b9d65a ]

of_find_matching_node_and_match() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
