[PATCH v2 01/10] sunxi: sun60i: initial support for A733 SoC

[Yixun Lan]

Add basic support for Allwinner A733 SoC.

- Include some basic register definitions
- Introduce a new SUN60I A733 Kconfig option
- Ssetup RVBAR register properly according to docs
- Config max DDR size 16GB
- Config SRAM 0x62000 for TF-A

Signed-off-by: Yixun Lan <dlan at gentoo.org>

---
Note, Address for TF-A can be altered to other value, for example,
moving it to the DDR address space. The only requirement is that
load and run address should be matched.
