Add support for the LinkSprite pcDuino 3 Nano board. This is a low-cost
Allwinner A20 board with Arduino-style GPIO headers; it features 1G RAM,
4G NAND flash, 1 micro-SD, 2 USB sockets, 1 micro USB socket for OTG and
another for power in, HDMI, SATA, 5V power for SATA devices, gigabit
Ethernet, an IR receiver, 3.5mm audio out and a MIPI camera connector.

For more details, see: http://linux-sunxi.org/LinkSprite_pcDuino3_Nano
