[PATCH v4 00/20] remove I2C_CLASS_DDC support

[Heiner Kallweit <hkallweit1@gmail.com>]

After removal of the legacy EEPROM driver and I2C_CLASS_DDC support in
olpc_dcon there's no i2c client driver left supporting I2C_CLASS_DDC.
Class-based device auto-detection is a legacy mechanism and shouldn't
be used in new code. So we can remove this class completely now.

Preferably this series should be applied via the i2c tree.

v2:
- change tag in commit subject of patch 03
- add ack tags
v3:
- fix a compile error in patch 5
v4:
- more ack and review tags
