icE1usb fw/gpsdo: Limit the fine tuning range
Fine tuning has a limited tuning range. If at some point we
hit the limits, we need to bit the bullet and try to 'transfer'
some of that to the coarse range as best as we can. Hopefully
we get it close enough to limit disruption.
Note that this should really never happen because although it's
limited, the tuning range should be good enough to absorb any
reasonable temperature / aging variation once we have coarse tuned.
