m68knommu: remove is_in_rom() function
Remove is_in_rom() function. It doesn't actually serve the purpose it was intended to. If you look at the use of it _access_ok() (which is the only use of it) then it is obvious that most of memory is marked as access_ok. No point having is_in_rom() then, so remove it.
