This driver implements support for the Winbond W83627EHF, W83627EHG,
W83627DHG, W83627DHG-P, W83667HG, W83667HG-B, W83667HG-I (NCT6775F),

(NCT6775F), and NCT6776F super I/O chips. We will refer to them collectively
as Winbond chips.
The chips implement three temperature sensors (up to four for 667HG-B, and nine
for NCT6775F and NCT6776F), five fan rotation speed sensors, ten analog voltage
sensors (only nine for the 627DHG), one VID (6 pins for the 627EHF/EHG, 8 pins
for the 627DHG and 667HG), alarms with beep warnings (control unimplemented),
The chips implement 2 to 4 temperature sensors (9 for NCT6775F and NCT6776F),
2 to 5 fan rotation speed sensors, 8 to 10 analog voltage sensors, one VID
(except for 627UHG), alarms with beep warnings (control unimplemented),
and some automatic fan regulation strategies (plus manual fan control mode).
