Hi Jean (and all),

Add pwm support to the f71882fg driver. Changes made by me to the latest
revision submitted by Mark van Doesburg:
-Remove whitespace only changes from the patch (undo Lindent damage)
-Change pwm#_auto_point#_temp unit from degrees to milli degrees celcius
-Remove incomplete ability to turn of pwm (pwm#_enable = 0), as the hardware
  does not support this
-Made handling of out of range input to sysfs files more robust
-When we write a new setting to IC update our local cached copy of the register
  being written
