[U-Boot] [PATCH v2 1/4] sunxi: add basic V3s support

Tue Jan 10 10:18:22 CET 2017
Basic U-Boot support is now present for V3s.
Some memory addresses are changed specially for V3s, as the original
address map cannot fit into a so small DRAM.
As the DRAM controller code needs a big refactor, the SPL support is
disabled in this version.
