add common fan control asic callbacks
Adds 4 callbacks for managing fan state/speed
* fan_ctrl_set_mode - manages fan control mode (nonzero == manual)
* fan_ctrl_get_mode - queries fan control mode
* set_fan_speed_percent - manages fan speed as percentage value
* get_fan_speed_percent - queries fan speed as percentage value
