clk: highbank: fix refcount leak in hb_clk_init()
commit 5eb8ba90958de1285120dae5d3a5d2b1a360b3b4 upstream.
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.
