hwmon: w83627ehf updates
Add control of fan minimum turn-on output levels, decoupling it from the
fan turn-off output level. Add control of rate of change of fan output
level. These in turn allow lower turn-off rotor speed and smoother
transitions for better thermal and acoustic control authority. Add
support for constant fan speed and proportional-response operations modes.
