This adds support for a rt5350-based "portable nas" solution
from Intenso. The board comes with 32M RAM and 8M Flash, the
built-in HDD is connected/accessible via a usb3.0<->sata
bridge VLI VL701.

The device has 1 Ethernet port (100M/10M), 1 micro b usb 3.0
socket (for charging the battery, or accessing the hdd directly).
Wireless connectivity is provided by the rt5350 SoC [i.e.:
802.11n 1x1 2.4 GHz with a pcb antenna.]

Serial, leds, wifi, ethernet and usb are tested and
as far as I can tell: they are working fine (tm).
