clk: dove: fix refcount leak in dove_clk_init()

[ Upstream commit 8d726c5128298386b907963033be93407b0c4275 ]

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.
