gpu: ipu-v3: Do not bail out on missing optional port nodes
The port nodes are documented as optional, treat them accordingly. Reported-by: Martin Fuzzey <mfuzzey@parkeon.com> Reported-by: Chris Healy <Chris.Healy@zii.aero> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Fixes: 304e6be652e2 ("gpu: ipu-v3: Assign of_node of child platform devices to corresponding ports")
