configurations: catalina_pdb: Use current reading for cable tsense

The Catalina system previously used shunt voltage (`in0`) to calculate
the NCT thermistor value for the cable temperature sensor. However, the
hwmon driver represents voltage in millivolts (mV), while the shunt
voltage for the cable tsense is typically less than 1 mV.

Switch to using the current (`curr1`) reading to compute the NCT
thermistor value, providing more accurate and reliable temperature
measurements for the cable tsense sensors.
