[PATCH 4.14 054/343] clk: mv98dx3236: fix refcount leak in mv98dx3236_clk_init()

From: Greg Kroah-Hartman

[ Upstream commit 9b4eedf627045ae5ddcff60a484200cdd554c413 ]

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.
