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

Browse source

[ Upstream commit 26c2b7d9fa ]

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.
