optimus: enable at24c512 and lm96163 (lm96063) drivers on i2c bus.

Note: this required fixing a bug in i2c-comcerto.c so that it would use a
hardcoded bus id rather than auto-allocating a bus id one more than the
largest predefined device.  The old behaviour guaranteed that the predefined
devices were never on the same bus as the actual bus, so they would never
be seen, which is exactly wrong.
