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.

SPM: Map memory regions from RD ...

SPM needs to map a number of regions on behalf of the secure partition.
Previously, it used to get a list of them from platform code using the
plat_get_secure_partition_mmap() API. Now it gets them from the resource
description structure.

The SPM<->SP shared buffer is mapped dynamically at EL3. This buffer is
used to pass information between SPM and SP, so it must be mapped at EL3
as well in order to be used by SPM.

Dynamic translation tables have been enabled when the Trusted Firmware
is compiled with SPM support.

MULTI_CONSOLE_API fixes and cleanups

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.

plat/common/crash_console_helpers.S: Fix MULTI_CONSOLE_API support ...

Crash reporting via the default consoles registered by MULTI_CONSOLE_API
has been broken since commit d35cc34 (Console: Use callee-saved
registers), which was introduced to allow console drivers written in C.
It's not really possible with the current crash reporting framework to
support console drivers in C, however we should make sure that the
existing assembly drivers that do support crash reporting continue to
work through the MULTI_CONSOLE_API.

This patch fixes the problem by creating custom console_putc() and
console_flush() implementations for the crash reporting case that do not
use the stack. Platforms that want to use this feature will have to link
plat/common/aarch64/crash_console_helpers.S explicitly.

Also update the documentation to better reflect the new reality (of this
being an option rather than the expected default for most platforms).

plat/common: Remove duplication of plat_crash_console functions/stubs ...

Commit e74afb652 (Deprecate weak crash console functions) deprecated the
default inclusion of weak definitions for plat_crash_console functions
in plat/common/aarch64/platform_helpers.S. The code was later copied out
to plat/common/aarch64/crash_console_helpers.S so platforms can link it
explicitly if they want to. However, since deprecation does not mean
removal, the same code is also still duplicated in platform_helpers.S.

The duplicated code contains both empty stubs for the !MULTI_CONSOLE_API
case, and a real implementation that used to work but was broken by
commit d35cc34 (Console: Use callee-saved registers) for
MULTI_CONSOLE_API. It's not great to have both of these duplicated in
two files, so this patch splits them up: in platform_helpers.S we'll
only keep the empty stubs (guarded by !ERROR_DEPRECATED), which should
not regress functionality since the MULTI_CONSOLE_API implementation was
already broken anyway. In crash_console_helpers.S, we'll only keep the
MULTI_CONSOLE_API version, which is enough both as an implementation in
itself and as a sample for how to reimplement these functions in a
platform-specific file.
