Jean Delvare 4101ece3a2 hwmon: Fix chip feature table headers 
These got broken by recent patches fixing checkpatch warnings in these
drivers. The trick is that the patches themselves looked good, but the
source files after applying them do not. That's why I am not a big fan
of using tabs inside comments.
