More table cleanups.

Wrap SHA256 hashes in `<code/>` so they'll all be visually the same length.

Make the references from DSP1 and DSP1B to the notes below more obviously
references, not content.

Reword the DSP1 note so that it makes sense even if you didn't just come
from the DSP1/1A row of the table.
