Subject: [PATCH] ARM: dts: sun5i: a13: Add Olimex SOM board dts support

From: Jagan Teki <jagan@...nedev.com>

Add support for Olimex A13-512-SOM board, and this particular
design is like A13-SOM-WIFI can mount on-top of A13-SOM.

https://www.olimex.com/Products/SOM/A13/A13-SOM-512/
https://www.olimex.com/Products/SOM/A13/A13-SOM-WIFI/open-source-hardware

Features:
- A13 Cortex A8 processor at 1GHz, 3D Mali400 GPU
- 512MB DDR3 memory
- MicroSD card connector
- UART console connector
- Status LEDs
- BL-8188-8M WiFi wireless module with Realtek RTL8188CUS chip
- USB-OTG with mini USB connector
