google/kukui: Adjust LCM ID voltages
Currently some of the LCM ID voltage gaps are below 100mV. For example, the
voltage difference between ID 2 and 3 is 503-440=63mV. To reduce the risk of
misrecognition from the hardware level, the voltages are adjusted so that all
the voltage gaps are larger than 100mV. The RD2 resistor values are also
updated.
