soc_core: additional CSR safety assertions
...
Since csr_data_width=64 has probably never worked properly, remove
it as one of the possible options (to be fixed and re-added later).
Add csr_data_width=16, which has been tested and does work.
Additionally, ensure csr_data_width <= csr_alignment (we should not
attempt to create (sub)registers larger than the CPU's native word
size or XLen).
