Intriniscs reading or writing the FFR register need to model the fact
there is additional state being read/wrtten.

Model this state as inaccessible memory.

- setffr => write inaccessiblememonly
- rdffr => read inaccessiblememonly
- ldff* => read arg memory, write inaccessiblemem
- ldnf => read arg memory, write inaccessiblemem
