cell0 and cell1 are output-only constant value devices. They are
to drive constant 0 or 1 to the input of something else. The cell
types are completely defined in the EDIF you posted. If Lattice
tools can't handle it, they need to be slapped around until they
explain why they don't support LPM_CONSTANT cells.
