mb/google/kukui: change Jacuzzi followers LCMID to fixed value

The LCM ID is not really used on Jacuzzi followers and the reference
design expects ADC to return 0. However, there were hardware design
issues so the returned value became unexpected numbers.

 - Juniper and Kappa returns 1.
 - Burnet and Esche returns 1 on normal boot, and 0 on recovery boot.
 - Cerise and Stern usually returns 0, and sometimes 1.

To fix that, we are changing LCM ID to fixed value for Jacuzzi followers.
