* Add myself to debian/copyright
* Add script dtb-probe/kirkwood-linkstation, based on dtb-probe/kirkwood-qnap,
  to support smooth upgrade/downgrade of kernel, since there's a split/rename
  for device tree file of a few Buffalo Linkstation devices.
* Make use of above script to determine DTB file for listed devices:
  - Buffalo Linkstation LS-VL
  - Buffalo Linkstation LS-WSXL
  - Buffalo Linkstation LS-WVL
  - Buffalo Linkstation LS-WVL/VL
  - Buffalo Linkstation LS-WXL
  - Buffalo Linkstation LS-WXL/WSXL
* Update "DTB-Append-From" field for "Buffalo Linkstation Pro/Live", since
  the patch of device tree is backported to sid (4.4) kernel.
* Update machine ID for "Buffalo Linkstation Mini (LS-WSGL)"
