This patch adds DT board setup for the LaCie NAS Network Space Mini v2 (aka SafeBox). The hardware characteristics are very close to those of the Network Space Lite v2. The main difference are: - A GPIO fan which is only available on the NS2 Mini. - A single USB host port is wired on the NS2 Mini. The NS2 Lite provides an additional dual-mode USB port (host/device).
