csky: Don't leak device tree node reference
of_find_node_by_type() acquires a reference to the node returned by it and that reference needs to be dropped by its caller. setup_smp() doesn't do that, so fix it by converting to for_each_of_cpu_node(). Signed-off-by: Yangtao Li <tiny.windzz@gmail.com> Signed-off-by: Guo Ren <guoren@kernel.org>
