sunxi: add Linksprite pcDuino v1/v2 support
Add support for a sun4i board built by Linksprite. This addition covers both v1 and v2 versions. As the board has been working with 408MHz memory setting in the u-boot-sunxi branch, and has been proven to be running stable during my tests as well, a respective new DRAM config file is added as well.
