[media] saa7164: fix format ioctls
Fix various v4l2-compliance issues in the formatting ioctls: - the vbi device implemented video format ioctls which make no senses for a vbi device, remove them. - remove the unused ts_packet_size and ts_packet_count fields. - fill in colorspace and field. - fill in sizeimage with a default value. - for the video node the get, set and try format functions all do the same thing, so combine into a single function.
