meta: terminus: adjust the index value in terminus NIC

Because unable to read the threshold setting in the
Terminus NIC, adjust the index value according to the
item name.

Tested:
- Check the threshold of the NIC temperature sensor

~# mfg-tool sensor-display | table-sensor-display | grep NIC
sensor     ...  units    ... UCR UNR
---------- ...  -------- ... --- ---

NIC0_TEMP_C     DegreesC     105 115
NIC1_TEMP_C     DegreesC     105 115
NIC2_TEMP_C     DegreesC     105 115
NIC3_TEMP_C     DegreesC     105 115
