video: fbdev: amba-clcd: Fix refcount leak bugs

In clcdfb_of_init_display() we should call of_node_put() for the references returned by of_graph_get_next_endpoint() and of_graph_get_remote_port_parent() which have increased the refcount.

Besides we should call of_node_put() both in fail path or when the references are not used anymore.
