[PATCH 4.14 053/343] clk: armada-xp: fix refcount leak in axp_clk_init()

From: Yangtao Li <tiny.windzz@xxxxxxxxx>

[ Upstream commit db20a90a4b6745dad62753f8bd2f66afdd5abc84 ]

The of_find_compatible_node() returns a node pointer with refcount
incremented, but there is the lack of use of the of_node_put() when
done. Add the missing of_node_put() to release the refcount.
