Add GE1/1 VFAT FEAST voltage monitoring

Laurent Petre requested to merge feature/ge11-vfat-voltages into main


The title should speak for itself.

Also includes various bug fixes or enhancements related to the SCA-based monitoring.

  • Ensure that the ADC conversions are over before retrieving the measurement, even in the case of an AXI bus error.
  • Make use of the 1kOhm precision resistor to calibrate the ADC current source (improve dramatically the PT100/PT1000 precision).
  • Export the raw ADC counts in the JSON monitorable object for debugging purposes.
