[PATCH] staging: olpc_dcon: Remove I2C_CLASS_DDC support

olpc_dcon is the only remaining i2c client device driver declaring
I2C_CLASS_DDC support after the legacy eeprom driver has been removed.

olpc_dcon is only used on olpc devices, connected to an i2c adapter
driven by scx200_acb. This adapter driver declares support for
I2C_CLASS_HWMON and I2C_CLASS_SPD. Therefore we can safely drop
I2C_CLASS_DDC support in olpc_dcon.

That's the last step before I2C_CLASS_DDC can be removed in general.

This patch is solely based on documentation, and I don't have an olpc
device for testing. Therefore some testing would be appreciated before
patch is applied.
