stm32mp1: dynamically map DDR later and non-cacheable during its test
...
A speculative accesses to DDR could be done whereas it was not reachable
and could lead to bus stall.
To correct this the dynamic mapping in MMU is used.
A first mapping is done for DDR tests with MT_NON_CACHEABLE attribute,
once DDR access is setup. It is then unmapped and a new mapping DDR is done
with cacheable attribute (through MT_MEMORY) to speed-up BL33 (or OP-TEE)
load.
The disabling of cache during DDR tests is also removed, as now useless.
A call to new functions stm32mp_{,un}map_ddr_non_cacheable() is done
instead.
PLAT_XLAT_TABLES_DYNAMIC is activated globally as used in BL2 and BL32.
BL33 max size is also updated to take into account the secure and shared
memory areas. Those are used in OP-TEE case.

stm32mp1: platform.mk: support generating multiple images in one build
...
Board Support for the stm32mp1 platform is contained in the device tree,
so if we remove hardcoding of board name from the Makefile, we can build
the intermediary objects once and generate one new tf-a-*.stm32 binary
for every device tree specified. All in one go.
With implicit rules implemented, we only need to change the top level
target to support multi-image builds on the stm32mp1.

stm32mp1: platform.mk: use PHONY for the appropriate targets
...
Currently, building TF-A for STM32MP1 triggers a full rebuild,
avoid this by removing the .PHONY: specification for the final image and
replace it by specifying PHONYness for the targets that don't actually
produce file output.
This will come in handy in follow-up commits, when implicit rules are
introduced, as implicit rule search is skipped for .PHONY targets.

stm32mp1: add watchdog support
...
Introduce driver for STM32 IWDG peripheral (Independent Watchdog).
It is configured according to device tree content and should be enabled
from there.
The watchdog is not started by default. It can be started after an HW
reset if the dedicated OTP is fused.
The watchdog also needs to be frozen if a debugger is attached.
This is done by configuring the correct bits in DBGMCU.
This configuration is allowed by checking BSEC properties.
An increase of BL2 size is also required when adding this new code.

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.

drivers/console: Link console framework code by default
...
This patch makes the build system link the console framework code by
default, like it already does with other common libraries (e.g. cache
helpers). This should not make a difference in practice since TF is
linked with --gc-sections, so the linker will garbage collect all
functions and data that are not referenced by any other code. Thus, if a
platform doesn't want to include console code for size reasons and
doesn't make any references to console functions, the code will not be
included in the final binary.
To avoid compatibility issues with older platform ports, only make this
change for the MULTI_CONSOLE_API.
