hwmon: (pwm-fan) Make SENSORS_PWM_FAN depend on OF

This driver won't instantiate if OF is not configured, thus add OF dependency.
Also add COMPILE_TEST to increase build testing coverage.

          If you say yes here you get support for fans connected to PWM lines.
          The driver uses the generic PWM interface, thus it will work on a
