feat(st): adapt stm32 linker scripts for clang

With Clang, the address inside a section does not seem relative to its
start address. Use ABSOLUTE keyword for those addresses.
For stm32 binary containing BL2 and its DT, we can use that as PIE is
not used (either disabled or used with BL2_IN_XIP_MEM).
This is still working with GCC.

feat(plat/st): use FIP to load images

BL2 still uses the STM32 header binary format to be loaded from ROM code.
BL32 and BL33 and their respective device tree files are now put together
in a FIP file.
One DTB is created for each BL. To reduce their sizes, 2 new dtsi file are
in charge of removing useless nodes for a given BL. This is done because
BL2 and BL32 share the same device tree files base.

The previous way of booting is still available, the compilation flag
STM32MP_USE_STM32IMAGE has to be set to 1 in the make command. Some files
are duplicated and their names modified with _stm32_ to avoid too much
switches in the code.

stm32mp1: add OP-TEE support

Support booting OP-TEE as BL32 boot stage and secure runtime
service.

OP-TEE executes in internal RAM and uses a secure DDR area to store
the pager pagestore. Memory mapping and TZC are configured accordingly
prior OP-TEE boot. OP-TEE image is expected in OP-TEE v2 format where
a header file describes the effective boot images. This change
post processes header file content to get OP-TEE load addresses
and set OP-TEE boot arguments.

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
