sunxi: Add defconfig and dts for the Polaroid MID2809PXE4 tablet 

The Polaroid MID2809PXE4 is a 9" tablet which is clearly marked
Polaroid MID2809PXE4 on the back. It features a 9" 16:9 800x480 LCD,
A23 Soc, 1GB RAM, 8GB NAND, gsl3670 touchscreen and esp8089 wifi.

The dts file is identical to the one submitted to the upstream kernel.
