[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.

* This is a dummy non-zero value for the sizeimage field of v4l2_pix_format.
* It is not actually used for anything since this driver does not support

This is not considered a good practice anymore, as it makes harder to grep for strings at the source code. As we're right now fixing other drivers due to KERN_CONT, we need to be able to identify what printk strings don't end with a "\n". It is a way easier to detect those if we don't break long lines. So, join those continuation lines.
