[PATCH] irqchip/gic/realview: Fix refcount leak in realview_gic_of_init

[Miaoqian Lin <linmq006@gmail.com>]

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.

Fixes: 82b0a434b436 ("irqchip/gic/realview: Support more RealView DCC variants")
