[PATCH] drivers: soc: atmel: Fix refcount leak in atmel_soc_device_init

[Miaoqian Lin]

of_find_node_by_path() 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.

Fixes: 960ddf70cc11 ("drivers: soc: atmel: Avoid calling at91_soc_init on non AT91 SoCs")
