- Cleanup whitespace and extra ()s in vtophys() macros.

- Move vtophys() macros next to vtopte() where vtopte() exists to match
  comments above vtopte().
- Remove references to the alternate address space in the comment above
  vtopte().  amd64 never had the alternate address space, and i386 lost it
  prior to PAE support being added.
- s/entires/entries/ in comments.
