Subject: [PATCH] ARM: integrator: Fix refcount leak in intcp_init_of
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: df36680f1a71 ("ARM: integrator: core module registers from compatible strings")
