hwmon: (pwm-fan) stop using legacy PWM functions and some cleanups
pwm_apply_state() does what the legacy functions pwm_config() and
pwm_{en,dis}able() do in a single function call. This simplifies error
handling and is more efficient for new-style PWM hardware drivers.
Instead of repeatedly querying the PWM framework about the initial PWM
configuration, cache the settings in driver data.
Also use __set_pwm() in .probe() to have the algorithm calculating the PWM
state in a single place.
