All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.
The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.
The exceptions are files that are imported from other projects:
- CryptoCell driver
- dt-bindings folders
- zlib headers

The SRAM in the Allwinner H6 SoC starts at 0x2000, with the last part
ending at 0x117fff (although with gaps in between).
So SUNXI_SRAM_SIZE should be 0xf8000, not 0x98000.
Fix this to map the arisc exception vector area, which we will need
shortly.

At the moment we map as much of the DRAM into EL3 as possible, however
we actually don't use it. The only exception is the secure DRAM for
BL32 (if that is configured).
To decrease the memory footprint of ATF, we save on some page tables by
reducing the memory mapping to the actually required regions: SRAM, device
MMIO, secure DRAM and U-Boot (to be used later).
This introduces a non-identity mapping for the DRAM regions.

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".
