This adds streams support to TI CAL driver (and two minor improvements).

The previous version was sent in 2023, but there has been no changes
except from rebasing to upstream.

Changes in v6:
- Rebase on top of v4.16-rc7
- Add two small patches (not related to streams as such)
- Dropper the metadata patch for now, to make the series apply to plain
  upstream
- Link to v5: https://lore.kernel.org/r/20230918-cal-streams-v5-0-4851f073f58a@ideasonboard.com

Changes in v5:
- Some improvements in the patch description of the first patch
- Add "media: ti: cal: Add metadata streams support"
- Link to v4: https://lore.kernel.org/r/20230808-cal-streams-v4-1-1f37610e0946@ideasonboard.com

Changes in v4:
- A few minor formatting changes
- Small changes regarding how the code handles metadata formats.
  No metadata formats are supported yet, but we do have some code to
  ensure that metadata formats aren't allowed on video nodes in video
  capture mode. A future patch will enable metadata capture, allowing
  the runtime change of video nodes between video and meta capture.
- Link to v3: https://lore.kernel.org/all/20230302100755.191164-6-tomi.valkeinen@ideasonboard.com/
