drivers/video/backlight/88pm860x_bl.c: add missing of_node_put()
of_find_node_by_name() returns a node pointer with refcount incremented, use of_node_put() on it when done. of_find_node_by_name() will call of_node_put() against the node pass to from parameter, thus we also need to call of_node_get(from) before calling of_find_node_by_name().
