sunxi: Add support for A33-OLinuXino board

A33-OLinuXino is A33 development board designed by Olimex LTD.

It has AXP223 PMU, 1GB DRAM, a micro SD card, one USB-OTG connector,
headphone and mic jacks, connector for LiPo battery and optional
4GB NAND Flash.

It has two 40-pin headers. One for LCD panel, and one for
additional modules. Also there is CSI/DSI connector.

The dts files are identical to the ones submitted to the upstream kernel.
