[ Upstream commit a2106f38077e78afcb4bf98fdda3e162118cfb3d ]

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: 5e68c0fc8df8 ("soc: amlogic: Add Meson6/Meson8/Meson8b/Meson8m2 SoC Information driver")
