  Log:
  If the disk reports that it support the Compact Flash Association command
  set, announce BIO_DELETE capability and issue ATA_CFA_ERASE when we get one.
  
  Once we issue more BIO_DELETE, this will improve lifetime, and
  possibly write speed of Flash based devices which have usable flash
  adaptation layers.
  
  For now, about the only usage is the newfs(1) -E flag.
