Calibration data are now stored in a sdbfs file, not anymore in the
ipmi internal use area.
Using sdb-read to get the calibration data file.

Erase eeprom before reading content from binary file.

Aquired data seems wrong (bug in data path?).
Computer hangs after a few acquisitions.

Can't find out what was the changes...

- End of acquisition interrupt is generated when the DDR write FIFO is empty.
- Updated DDR core.

Checks that the offset and gain errors are within the specified % of the FS.

Add temperature (during calibration) read from EEPROM calibration data.

Add FMC temperature in the calibration data to be stored in the EEPROM.
Write measurement values to a file (for validation in another test).
