diffs from Paul de Weerd;
ok deraadt@

- refer to the section 4 manual page for every device target, whenever

- repair a few minor quoting errors
- repair a few sorting errors
- fix a few device descriptions (ideally they would be synched with the
.Nd line of their manpages, but we are not there... yet)
- minor mdoc fixes

- sort devices inside sections
- make sure all platforms provide a local target (sigh)
- remove a few dead devices not worth mentioning on a few arches while there.

fragments to be overriden.
No functional change (yet).
