drm/omap: dss: Fix refcount leak bugs
[ Upstream commit 8b42057e62120813ebe9274f508fa785b7cab33a ]
In dss_init_ports() and __dss_uninit_ports(), we should call
of_node_put() for the reference returned by of_graph_get_port_by_id()
in fail path or when it is not used anymore.
Fixes: 09bffa6e5192 ("drm: omap: use common OF graph helpers")
