Tidy NOTES a bit:

- ath(4) is the last listed device, so make it's comment last as well
- since we have hints for le(4), bring it back by inserting commented
  out line until I check, if it can be safely enabled.
- bring snc(4) explanation
- put pmtimer comment together with other drivers' comments in a block
- bring comments for canbus, canbepm, pmc

olpt comment has been left blank, since I don't know how does this
driver differ from other printer drivers.
