clk: ti: fix refcount leak in ti_dt_clocks_register()

Browse source 
[ Upstream commit 2274d8001fbb5e1942fbcab5ad2eb15553b09ed2 ]

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.
