hwmon: (lm85) Implement the standard PWM frequency interface

Browse Source 
Implement the standard PWM frequency interface: pwm[1-*]_freq in
units of 1 Hz, instead of the non-standard pwm[1-*]_auto_pwm_freq
in units of 0.1 Hz. The old naming was not only non-standard, it was
also confusing, because it suggested that the frequency value only
applied in automatic fan speed mode, which isn't true.

* pwm#_auto_pwm_min - this specifies the PWM value for temp#_auto_temp_off
temperature. (PWM value from 0 to 255)
* pwm#_auto_pwm_freq - select base frequency of PWM output. You can select
in range of 10.0 to 94.0 Hz in .1 Hz units.
(Values 100 to 940).
The pwm#_auto_pwm_freq can be set to one of the following 8 values. Setting the
frequency to a value not on this list, will result in the next higher frequency
being selected. The actual device frequency may vary slightly from this
specification as designed by the manufacturer. Consult the datasheet for more
details. (PWM Frequency values: 100, 150, 230, 300, 380, 470, 620, 940)
* pwm#_auto_pwm_minctl - this flags selects for temp#_auto_temp_off temperature
the bahaviour of fans. Write 1 to let fans spinning at
pwm#_auto_pwm_min or write 0 to let them off.
