  This part only concerns the rework of the CSI driver to support the MIPI CSI-2
and ISP workflows.

Every patch was reviewed at this point and the whole thing looks good to go.
Since this multi-part series has been going on for a while, it would be great
to see it merged soon!

Changes since v6:
- Removed merged patches;
- Added collected tags;
- Rebased on the latest media tree;
- Followed media/video pipeline helpers changes.

Changes since v5:
- Rebased on latest media tree;
- Switched to using media_pad_remote_pad_first;
- Switched to using media_pad_remote_pad_unique;
- Declared variant const to avoid a warning.

Changes since v4:
- Removed the v4l2 controls handler from the driver;
- Removed the info message about video device registration;
- Fixed "literature" typos;
- Moved patches dependent on the ISP driver to its dedicated series;
- Rebased on the latest media tree;
- Added collected tags;

Changes since v3:
- Updated Kconfig to follow the latest media-wide changes;
- Rebased on latest changes to the driver (JPEG/sRGB colorspaces);
- Added helper to get a single enabled link for an entity's pad, to replace
  source selection at link_validate time and select the remote source at
  stream on time instead;
- Kept clock-managed regmap mmio;
- Added collected review tags;
- Various cosmetic cleanups;

Changes since all-in-one v2:
- Reworked capture video device registration, which stays in the main path.
- Reworked async subdev handling with a dedicated structure holding the
  corresponding source to avoid matching in the driver;
- Added mutex for mbus format serialization;
- Remove useless else in link_validate;
- Reworked commit logs to include missing information;
- Cleaned up Kconfig, added PM dependency;
- Moved platform-specific clock rate to of match data;
- Added collected Reviewed-by tags;
- Updated copyright years;
