media: Accept non-subdev sinks in v4l2_create_fwnode_links_to_pad()
The v4l2_create_fwnode_links_to_pad() helper requires the sink pad
passed to it to belong to a subdev. This requirement can be lifted
easily. Make the function usable for non-subdev sinks, which allows
using it with video_device sinks.
