configs/friendlyarm_nanopi_neo_defconfig: new defconfig

This patch adds a new defconfig for the NanoPi NEO board made by
FriendlyARM. This board is based on the Allwinner H3 SoC.

See: https://wiki.friendlyelec.com/wiki/index.php/NanoPi_NEO

This patch uses the mainline kernel and u-boot for the board.

The configurations are based on the previously dropped defconfig
maintained by Yann E. MORIN <[email protected]>.

+Nanopi NEO
+
+Intro
+=====
+
+This default configuration will allow you to start experimenting with the
+buildroot environment for the NanoPi NEO. With the current configuration
+it will bring-up the board, and allow access through the serial console.
+
+FriendlyARM Nanopi NEO link:
+https://wiki.friendlyelec.com/wiki/index.php/NanoPi_NEO
+
+How to build
+============
+
+    $ make friendlyarm_nanopi_neo_defconfig
+    $ make
+
+Note: you will need access to the internet to download the required
+sources.
+
+How to write the SD card
+========================
+
+Once the build process is finished you will have an image called "sdcard.img"
+in the output/images/ directory.
+
+Copy the bootable "sdcard.img" onto an SD card with "dd":
+
+  $ sudo dd if=output/images/sdcard.img of=/dev/sdX
+  $ sudo sync
+
+Insert the micro SD card in your Nanopi NEO and power it up. The console
+is on the debug TTL UART, 115200 8N1.
+
+Ethernet
+==========
+
+  # udhcpc -i eth0
+
+Enjoy!
