[U-Boot] [PATCH v5 1/3] sunxi: add basic V3s support

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.

Changes in v5:
- Fixed a regression issue on AArch64 sunxi build.
Changes in v4:
- Enable PSCI for the SoC. (For virtualization support, although it
seems to be a joke to use virtualization on systems with 64MiB DRAM)
- Add Maxime's ACK and Jagan's Reviewed-By.
Changes in v3:
- Remove some dead codes.
