hwmon: (w83627hf) Drop reset module parameter 



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.

  The driver used to reset the chip on load, but does no more. Use

  'reset=1' to restore the old behavior. Report if you need to do this.
