This is a new kirkwood box made by Universal Scientific Industrial, Inc.
The product description is here:
http://www.usish.com/english/products_topkick1281p2.php
It is very similar to the dreamplug and other plug devices, with the
exception that it has room for a 2.5" SATA HDD internally.

- sorted topkick dtb Makefile entry alphabetically
Changes since V1:
- changes nr-ports to 1 for sata0
- included board in defconfig
- trimmed #includes
- added mvsdio init call
