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.

9db6e7f500 hwmon: (pwm-fan) split __set_pwm into locked/unlocked functions 
Regular calls to set_pwm don't hold the mutex, but the upcoming
update_enable support needs to call set_pwm with the mutex being held.
So provide the previous behavior in set_pwm (handling the lock), while
adding __set_pwm which assumes the lock being held.

b77f0c7680 hwmon: (pwm-fan) Simplify enable/disable check 
Instead of comparing the current to the new pwm duty to decide whether to
enable the PWM, use a dedicated flag. Also apply the new PWM duty in any
case. This is a preparation to enable/disable the regulator dynamically.

- g, h, j and cal5.

The coefficients can vary between product and product, so it can be very
useful to be able to modify them on the fly during the calibration
process.

The coefficients were added to device tree on top of the series property
(which can be used to select between series 5 and series 6), because
coefficients can vary between product and product, and code defaults might
not be accurate enough.
