There are some incorrect casts and some missing casts in the headers.
This patch fixes the ones that were 64-bit or 32-bit wide wrongly and
adds casts where they were missing.
Note that none of the changes of the patch actually changes the values
of the definitions. This patch is just for correctness.

Enforce full include path for includes. Deprecate old paths.
The following folders inside include/lib have been left unchanged:
- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}
The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).
For example, this patch had to be created because two headers were
called the same way: e0ea0928d5 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a2 ("drivers: add tzc380 support").
This problem was introduced in commit 4ecca33988 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.
Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

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

Erratum 855972 applies to revision r1p3 or earlier Cortex-A57 CPUs. The
recommended workaround is to disable instruction prefetch.

At present, various CPU register macros that refer to CPUACTLR are named
ACTLR. This patch fixes that.
The previous register names are retained, but guarded by the
ERROR_DEPRECATED macro, so as not to break platforms that continue using
the old names.

In order to avoid Undefined behavior, left operand in left-shift
expressions needs to be unsigned, and of sufficient size. The safest and
most consistent approach is to use unsigned long long type.

This patch makes all the defines in the CPU libraries unique,
by prefixing them with the CPU name.
NOTE: PLATFORMS USING THESE MACROS WILL HAVE TO UPDATE THEIR CODE
TO START USING THE UPDATED NAMES
