Drop the reset parameter of the w83627hf driver. It seems it wasn't that useful. It was dropped from the Linux 2.4 version of this driver back in July 2004. The only users who have reported that they were still using this parameter, needed it to switch the chip from automatic fan speed control back to manual mode. Now that the driver creates pwmN_enable sysfs files, users will be able to use these files instead, which is way less agressive.
