[PATCH v4 00/45] Allwinner A31/A83T MIPI CSI-2 and A31 ISP / CSI Rework

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 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;
