Subject: [PATCH v3 1/2] ARM: dts: sun7i: Add Iteaduino Plus A20

Iteaduino Plus A20 is very similar to Iteaduino Plus A10. In fact it
shares the same breakout board and the Itead Core A20 on top of it, is
only adapted to support the dual-core A20.

This commits enables the following hardware:

* HDMI Video output
* USB
* SATA (untested due to lack of hardware I could attach)
* Ethernet
* MMC storage
* UART
* USB OTG (untested, because I don't own an USB OTG cable/device)
