hwmon: (w83627ehf) The W83627DHG has 8 VID pins 



While the W83627EHF/EHG has only 6 VID pins, the W83627DHG has 8 VID
pins, to support VRD 11.0. Add support for this.

The chips implement three temperature sensors, five fan rotation

speed sensors, ten analog voltage sensors (only nine for the 627DHG), one

VID (6 pins), alarms with beep warnings (control unimplemented), and

some automatic fan regulation strategies (plus manual fan control mode).

Temperatures are measured in degrees Celsius and measurement resolution is 1

degC for temp1 and 0.5 degC for temp2 and temp3. An alarm is triggered when
