i2c: mlxcpld: Add callback to notify probing completion
Add notification to inform caller that driver probing has been completed. It allows to user, invoked platform device registration for "i2c-mlxcpld" driver, to be notified that bus adapter is available, and thus some devices could be connected to this bus.
