hwmon: (emc6w201) Fix DIV_ROUND_CLOSEST problem with unsigned divisors

Result of DIV_ROUND_CLOSEST is undefined for negative dividends if the divisor
variable type is unsigned. Fix by declaring divisor as signed variable.

hwmon: Driver for Nuvoton NCT6775F, NCT6776F, and NCT6779D

This driver will replace the w83627ehf driver for NCT6775F and NCT6776F,
and provides support for NCT6779D.

This patch provides support for voltage monitor attributes.

hwmon: (w83627ehf) Use fixed attributes for SYSTIN, CPUTIN, and AUXTIN on NCT6775/NCT6776

So far the code used dynamic temperature attributes for SYSTIN, CPUTIN, and
AUXTIN on NCT6775/NCT6776. That has the disadvantage that the mapping of
tempX_type and tempX_offset does not necessarily match reality, and code
complexity is increased.

To avoid mapping problems and simplify the code, use fixed mapping instead, and
use temp[4-9] for additional temperature sources.

hwmon: (w83627ehf) Add support for SmartFanIV mode on W83667HG-B

SmartFan IV mode is supported on W83667HG-B, but configured differently than
on other chips and not detected. As a result, changing the fan control mode
was impossible if SmartFan IV mode is selected.

Detect SmartFan IV mode and make it configurable if was configured at system
startup.
