[PATCH] ARM: highbank: Fix refcount leak in highbank_init

[Miaoqian Lin]

of_find_compatible_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.

Fixes: 220e6cf7b793 ("ARM: add Highbank core platform support")
