gpu: ipu-v3: Fix imx-ipuv3-crtc module autoloading 

If of_node is set before calling platform_device_add, the driver core
will try to use of: modalias matching, which fails because the device
tree nodes don't have a compatible property set. This patch fixes
imx-ipuv3-crtc module autoloading by setting the of_node property only
after the platform modalias is set.

Fixes: 304e6be652 ("gpu: ipu-v3: Assign of_node of child platform devices to corresponding ports")
