In newer Allwiner SoCs, the AA64nAA32 wires are mapped to a new register
called "General Control Register0" in the manual rather than the
"Cluster 0 Control Register0" in older SoCs.
Now the position of AA64nAA32 (reg and bit offset) is defined in a few
macros instead assumed to be at bit offset 24 of
SUNXI_CPUCFG_CLS_CTRL_REG0.

This works even on SoCs that do not have an ARISC, and it avoids
clobbering whatever ARISC firmware might be running.

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 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".
