Set the current to the target value when we're within one step rather than within tolerance to avoid undershooting the target.
Do not try and get the state when initialising the driver because it will fail to create the driver properly if the RF generator is unavailable on SICS startup. The current is zero when the RF gen is power cycled so it is safe to set the current reading and target current as zero in initialisation so we just set the operating frequency and everything else is left at zero.
