Alexander Stein b99152d4f0 hwmon: (pwm-fan) Switch regulator dynamically
This adds the enable attribute which is used to select if zero PWM duty
means to switch off regulator and PWM or to keep them enabled but
at inactive PWM output level.
Depending on the select enable mode, turn off the regulator and PWM if
the PWM duty is zero, or keep them enabled.
This is especially important for fan using inverted PWM signal polarity.
Having regulator supplied and PWM disabled, some PWM controllers provide
the active, rather than inactive signal.

With this change the shutdown as well as suspend/resume paths require
modifcations as well.
