Add fan pwm interface target

The current daemon only supports RPM-based fan control, whereas the
hwmon interface for PWM is often present.  This implements the Fan
Control PWM dbus interface.

This CL is not the complete solution, but if mixed with a follow-on CL
that does this, I think it'll be ideal.  For instance, this assumes the
pwm number matches, whereas the other CL lets you specify the
corresponding PWM target for the fan.
