allwinner: Add Allwinner H6 SoC support
The H6 is Allwinner's most recent SoC. It shares most peripherals with the
other ARMv8 Allwinner SoCs (A64/H5), but has a completely different memory
map.
Introduce a separate platform target, which includes a different header
file to cater for the address differences. Also add the new build target
to the documentation.
The new ATF platform name is "sun50i_h6".
