…orrect HSC current/power scaling

[Task Description]
Modify BIC (Server Board) temperature sensor thresholds and adjust HSC r_sense scaling to correct HSC current/power calculation.

[Motivation]

• Update and unify BIC temperature thresholds to match thermal policy and the management spreadsheet.
• Ensure HSC current/power measurements are correctly scaled by adjusting HSC r_sense to match actual hardware shunt/calibration.
• Provide verified sensor logs for BIC thermal and HSC power sensors.

[Design]
Update BIC (Server Board) sensor thresholds:

• MB_PCH_TEMP_C (0x04)

  • UCR = 71°C

• MB_SOC_CPU_TEMP_C (0x05)

  • UCR = 75°C
  • UNR = 78°C

• MB_DIMMA2_TEMP_C (0x06), MB_DIMMA3_TEMP_C (0x07), MB_DIMMA6_TEMP_C (0x0A), MB_DIMMA7_TEMP_C (0x0B)

  • UCR = 85°C

• MB_E1S_TEMP_C (0x0D)

  • UCR = 70°C

HSC related scaling:

• Adjust HSC r_sense from 0.25 -> 1
  • Purpose: correct current/power scaling used by the driver so HSC current/power sensors report accurate values that match hardware calibration/shunt configuration.

[Test Result]
Verified on GC2-ES platform using sensor-util. BIC related sensor outputs:
