Subject: [PATCH v4 0/8] Allwinner A31/A83T MIPI CSI-2 and A31 ISP / MIPI CSI-2 Support

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 MIPI CSI-2 controllers support changes.

Changes since v3:
- Updated Kconfig to follow the latest media-wide changes;
- Switched to clock-managed regmap mmio;
- Various cosmetic cleanups;
- Used endpoint-base instead of video-interface for "internal" endpoints
  in device-tree schema;
- Removed clock-lanes property in device-tree schema since lane reordering
  is not possible;

Changes since all-in-one v2:
- Use the newly-introduced media/mipi-csi2.h header instead of local
  definitions;
- Introduce a use a mutex for format access serialization;
- Make both port@0 and port@1 as well as ports required in the binding;
- Made one of the two CSI input ports required;
