allwinner: Introduce basic platform support
This platform supports Allwinner's SoCs with ARMv8 cores. So far they all sport a single cluster of Cortex-A53 cores. "sunxi" is the original code name used for this platform, and since it appears in the Linux kernel and in U-Boot as well, we use it here as a short file name prefix and for identifiers. This port includes BL31 support only. U-Boot's SPL takes the role of the primary loader, also doing the DRAM initialization. It then loads the rest of the firmware, namely ATF and U-Boot (BL33), then hands execution over to ATF. This commit includes the basic platform code shared across all SoCs. There is no platform.mk yet.
