hwmon: (nct6775) Add support for weighted fan control 

The NCT677X series support weighted fan control. In this mode, a secondary
temperature source is used in addition to the primary temperature source to
control fan speed. Add support for this feature.

@ -92,6 +92,25 @@ Common fan control attributes
pwm[1-5]_temp_sel Temperature source. Value is temperature sensor index.
For example, select '1' for temp1_input.
pwm[1-5]_weight_temp_sel
Secondary temperature source. Value is temperature
sensor index. For example, select '1' for temp1_input.
Set to 0 to disable secondary temperature control.
If secondary temperature functionality is enabled, it is controlled with the
following attributes.
pwm[1-5]_weight_duty_step
Duty step size.
pwm[1-5]_weight_temp_step
Temperature step size. With each step over
temp_step_base, the value of weight_duty_step is added
to the current pwm value.
pwm[1-5]_weight_temp_step_base
Temperature at which secondary temperature control kicks
in.
pwm[1-5]_weight_temp_step_tol
Temperature step tolerance.
