xlat_tables_v2: add base table section name parameter for spm_mm ...

Core spm_mm code expects the translation tables are located in the
inner & outer WBWA & shareable memory.
REGISTER_XLAT_CONTEXT2 macro is used to specify the translation
table section in spm_mm.

In the commit 363830df1c28e (xlat_tables_v2: merge
REGISTER_XLAT_CONTEXT_{FULL_SPEC,RO_BASE_TABLE}), REGISTER_XLAT_CONTEXT2
macro explicitly specifies the base xlat table goes into .bss by default.
This change affects the existing SynQuacer spm_mm implementation.
plat/socionext/synquacer/include/plat.ld.S linker script intends to
locate ".bss.sp_base_xlat_table" into "sp_xlat_table" section,
but this implementation is no longer available.

This patch adds the base table section name parameter for
REGISTER_XLAT_CONTEXT2 so that platform can specify the
inner & outer WBWA & shareable memory for spm_mm base xlat table.
If PLAT_SP_IMAGE_BASE_XLAT_SECTION_NAME is not defined, base xlat table
goes into .bss by default, the result is same as before.

Sanitise includes across codebase ...

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: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a282 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca33988b9 ("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.

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
