Currently, the I2C buses are probed for HWMON I2C devices, which might

a device tree flag, PROBE.
Yep.
Why do you need to do this? The OF conversion patch that is working
its way through the system lets you put the address of the device into
the device tree node. Probing shouldn't be necessary at all.
Currently I2C_CLASS_HWMON is used for all I2C adapters and therefore
probing is done even with a proper I2C node defined in the DTS file.
That's what the patch is fixing leaving the possibility to (re-)enable
legacy probing.
For some more details you may want to have a look to Jean's mail on that
