There was debate on the list and we decided that it would be more consistent with the rest of i2c if we defaulted to 100 kHz. ...but we never updated the bindings. Let's fix this. NOTE: since the i2c driver itself hasn't actually landed yet and the SoC here is very new it seems terribly unlikely that anyone was relying on the old 400 kHz number, so I'll assume this is an OK "incompatible" device tree change.
