irqchip/gic/realview: Fix refcount leak in realview_gic_of_init
[ Upstream commit f4b98e314888cc51486421bcf6d52852452ea48b ]
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.
