[lm-sensors] generic in and fan print code update headsup

[Hans de Goede]

Hi,

I'm working on and will shortly commit an update to the generic in and fan 
print code.

The in code currently will not print the ")" after printing the min voltage if 
an in input has a min limit but not a max.

The fan code currently will not print the divider for chips without a min 
limit, such as the fscpos ans fscher chips.

The update will fix this.

Regards,

Hans
