allwinner: Add Allwinner H616 SoC support
The new Allwinner H616 SoC lacks the management controller and the secure
SRAM A2, so we need to tweak the memory map quite substantially:
We run BL31 in DRAM. Since the DRAM starts at 1GB, we cannot use our
compressed virtual address space (max 256MB) anymore, so we revert to
the full 32bit VA space and use a flat mapping throughout all of it.
The missing controller also means we need to always use the native PSCI
ops, using the CPUIDLE hardware, as SCPI and suspend depend on the ARISC.
