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.

I'm fine with merging this patch through any of the trees that picks
up the rest of the patches.
