gpio: sifive: Fix refcount leak in sifive_gpio_probe

Browse Source 
[ Upstream commit 694175cd8a1643cde3acb45c9294bca44a8e08e9 ]

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