[PATCH] ARM: versatile: Fix refcount leak in ap_init_of

[Miaoqian Lin]

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: e67ae6be734d ("ARM: integrator: hook the AP into the SoC bus")
Fixes: df36680f1a71 ("ARM: integrator: core module registers from compatible strings")
