[media] s5p-g2d: Fix registration failure

Commit 1c1d86a1ea ("[media] v4l2: always require v4l2_dev,
rename parent to dev_parent") expects v4l2_dev to be always set.
It converted most of the drivers using the parent field of video_device
to v4l2_dev field. G2D driver did not set the parent field. Hence it got
left out. Without this patch we get the following boot warning and G2D
driver fails to register the video device.
