Subject: [PATCH] soc: integrator: Fix refcount leak in integrator_soc_init

of_find_matching_node() 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: f956a785a282 ("soc: move SoC driver for the ARM Integrator")
