arm64: dts: add Allwinner A64 SoC .dtsi

The Allwinner A64 SoC is a low-cost chip with 4 ARM Cortex-A53 cores
and the typical tablet / TV box peripherals.
The SoC is based on the (32-bit) Allwinner H3 chip, sharing most of
the peripherals and the memory map.
Although the cores are proper 64-bit ones, the whole SoC is actually
limited to 4GB (including all the supported DRAM), so we use 32-bit
address and size cells. This has the nice feature of us being able to
reuse the DT for 32-bit kernels as well.
This .dtsi lists the hardware that we support so far.
