Johannes Kirchmair ebb75a3c52 hwmon: (pwmfan) Do not force disable pwm controller ...

The pwm1_enable attribute of the pwmfan driver influences the mode of
operation, especially in case of a requested pwm1 duty cycle of zero.
Especially setting pwm1_enable to two, should keep the pwm controller
enabled even if the duty cycle is set to zero [1].

This is not the case at the moment, as the pwm controller is disabled
always if pwm1 is set to zero.

This commit tries to fix this behavior.
