ToT Tuning success message should include flavor

Currently, if you're tuning the ToT output of multiple FEs at a time, the first FE will log [TotTuning ] - SUCCESS ToT tuning was succesful! Mean ToT is 5.16 (target was 5.30) at VFF_DIFF = 47 without mentioning that it's only the DIFF flavor for now. Also the progressbar stops after the first successfully tuned FE.

The message should say that ToT was successfully tuned for DIFF and the progressbar should go on until all flavors are tuned.
