[PATCH] ppc64: Start the FCU in therm_pm72.c
Some G5 recent powermacs start with the fan control unit (FCU) disabled, by the firmware, causing the thermal control driver to break. We have to enable it before starting the feedback loops that set the fan speeds. This patch adds the code to start the FCU.
