VOL-1288 - OpenOLT Update driver to use new per-interface ranges

Updated OpenOLT driver to return a range of technology ranges as
determined through dynamic query of the device itself. Both
legacy board-wide and per-tech results are returned to the adapter
versions to maintain compatibility with adapters that do not yet
support the interface ranges.
