Luca Ceresoli c6ae0d9926 drm/arcpgu: fix device node leak 
commit ad3ac32a38 upstream.

This function gets a device_node reference via
of_graph_get_remote_port_parent() and stores it in encoder_node, but never
puts that reference. Add it.

There used to be a of_node_put(encoder_node) but it has been removed by
mistake during a rework in commit 3ea66a794f ("drm/arc: Inline
arcpgu_drm_hdmi_init").

Fixes: 3ea66a794f ("drm/arc: Inline arcpgu_drm_hdmi_init")
