Was causing trouble when called from pts.

- Fix the IPMI file.
- Add a 'name' file.
- Add a 'data/' dir.
- Change sdbfs layout.
- Rename ipmi.sdb in IPMI-FRU.
- Rename calibration.sdb in calib.

Was returning two channels per row.

The fmc adc mezzanine related cores are now in a wrapper with a wb crossbar.

The eeprom binary file was located inside the sdbfs input dir.
Causing gensdbfs to put it in the file list.

doc: Update calibration part, add computer date check (correct date needed for eeprom write test23).

Was keeping mfg date even if it was 0xffffff (uninitialised eeprom), or bigger than current date.

Work on acquisition (trig and end acq interrupts).
Work on internal trigger (level).

Instead of doing it at the end after all dma.

This function makes chained dma as big as possible, using up to 255 pages
for items and only one for the pattern.
