clk: armada-370: fix refcount leak in a370_clk_init()

BugLink: https://bugs.launchpad.net/bugs/1863019
[ Upstream commit a3c24050bdf70c958a8d98c2823b66ea761e6a31 ]

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.
