feat(allwinner): add function to detect H616 die variant

Allwinner provides a number of SoCs that use the same die as the H616.
Some of those chips apparently use a slight variation of that die, that
differs in the way the CPU cores' power and reset controls are handled.
This die variation can be detected by reading the SRAM version register.

Provide a predicate function that returns false if that die variant is
used. Since the CPU power control code is shared for all supported SoCs,
we provide an instance of this function for each SoC, as a static
inline, and return true on all other SoCs. This allows to always use
this function, and still let the compiler optimise away the unneeded
branch for those older SoCs.

This function is unused for now, but is needed in the next patch.

feat(allwinner): add SMCCC SOCID support

The Allwinner SID device holds a 16-bit SoC identifier, which we already
use in our code.

Export this number through the generic SMCCC SOCID interface, to allow
an architectural identification of an Allwinner SoC. This enables access
to this information from non-secure world, simplifies generic drivers
(ACPI comes to mind), and gives easy and precise access to the SoC ID
from userland in OSes like Linux.

Standardise header guards across codebase

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

allwinner: Introduce basic platform support

This platform supports Allwinner's SoCs with ARMv8 cores. So far they
all sport a single cluster of Cortex-A53 cores.

"sunxi" is the original code name used for this platform, and since it
appears in the Linux kernel and in U-Boot as well, we use it here as a
short file name prefix and for identifiers.

This port includes BL31 support only. U-Boot's SPL takes the role of the
primary loader, also doing the DRAM initialization. It then loads the
rest of the firmware, namely ATF and U-Boot (BL33), then hands execution
over to ATF.

This commit includes the basic platform code shared across all SoCs.
There is no platform.mk yet.

[Andre: moved files into proper directories, supported RESET_TO_BL31,
various clean ups and simplifications ]
