[PATCH] hwmon: Do not forcibly enable via686a by default
Do not enable the VIA VT82C686A/B integrated sensors by default, as
disabled sensors usually means that this feature is not used so the
values won't make any sense. This has been confusing many users in the
past:

http://www2.lm-sensors.nu/~lm78/readticket.cgi?ticket=1811
http://www2.lm-sensors.nu/~lm78/readticket.cgi?ticket=2052
It is still possible to forcibly enable the sensors by using the
force_addr module parameter.
