  SVN rev 222927 on 2011-06-10 10:13:40Z by mav
  
  MFC r222520:
  Add quirks to hint 4K physical sector (Advanced Format) for ATA disks not
  reporting it properly (none? of known disks now).
  
  Hitachi and WDC AF disks seem could be identified more or less formally.
  For Seagate and Samsung enumerate some found models/series.
  For other disks it can be forced with kern.cam.ada.X.quirks=1 tunable.
