This new version is an offspring from the big "Allwinner A31/A83T
MIPI CSI-2 Support and A31 ISP Support" series, which was split into
individual series for better clarity and handling.

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

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;
