An AST audit for dead code flags seven register-address constants that nothing
in the tree references. They are staying, and the files now say why at the
point of definition, so the next audit does not re-litigate them: the map costs
no logic and is kept COMPLETE on purpose, because three separate hardware bugs
came out of guessing it (the 0x4000-vs-0x8000 buffer base, NETLCKR, and the
60.3 ms settle). A partial map invites re-guessing the missing half. _TMSR in
particular documents where the second byte of the RMSR/TMSR = 0x55 burst lands.
Also fixed a real readability defect found while reading them: _RST_LOW_DEFAULT
and its two-line comment sat WEDGED BETWEEN _NETLCKR and the continuation of
_NETLCKR's own comment, so the sentence explaining the network lock finished on
the line declaring _NETLCK_UNLOCK. NETLCKR's note is now whole and in one
place, and _RST_LOW_DEFAULT sits after the register map with the 60.3 ms settle
mentioned alongside it, since the two waits are easy to confuse.
VERIFIED: generated RTLIL identical (9874 lines), so this is comment-only.
Both masters' testbenches pass.
