[U-Boot] [PATCH] sunxi: Add defconfig and dts for Difrence DIT4350 tablet

[Hans de Goede]

The Difrnce dit4350 tablet is a tiny tablet with a 4.3" 16:9 480x272 LCD,
A13 SoC, 512M RAM, 4G NAND, solomon systech ssd2532qn6 touchscreen at
i2c1 address 0x48, Memsic MXC622X accelerometer at i2c1 address 0x15 and
rtl8188etv wifi.

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