Add modes to phosphor-fan-control
phosphor-fan-control can behave differently based
on its command line arguments
--init: Set fans to full speed, delay for a
configurable amount of time to allow fans to ramp up,
start the fan control ready target, and then exit.
--control: Start the control algorithm. Never exits.
Will be started as part of the fan control ready target.
