Resolve the strange split between `read_CSR` (which is not `scattered`) and `ext_read_CSR` (which is). Same for `write_CSR` and `is_CSR_defined`.
I changed the return type of `read_CSR` from `option(xlenbits)` to `xlenbits` since the code must already check `is_CSR_defined` before calling `read_CSR`. The only function that returned `None()` was the `seed` CSR in `write_seed_csr`, which actually meant you would get a weird "Unhandled write to CSR" if you wrote to `seed`.
I renamed & reordered the files slightly to make the scattered mapping work, but I haven't moved any of the actual definitions yet. In future we should actually scatter them.
Fixes #410
