Thierry Reding 1db37f9561 pwm: cros-ec: Cache duty cycle value 
The ChromeOS embedded controller doesn't differentiate between disabled
and duty cycle being 0. In order not to potentially confuse consumers,
cache the duty cycle and return the cached value instead of the real
value when the PWM is disabled.
