NOTE: AARCH32/AARCH64 macros are now deprecated in favor of __aarch64__.
All common C compilers pre-define the same macros to signal which
architecture the code is being compiled for: __arm__ for AArch32 (or
earlier versions) and __aarch64__ for AArch64. There's no need for TF-A
to define its own custom macros for this. In order to unify code with
the export headers (which use __aarch64__ to avoid another dependency),
let's deprecate the AARCH32 and AARCH64 macros and switch the code base
over to the pre-defined standard macro. (Since it is somewhat
unintuitive that __arm__ only means AArch32, let's standardize on only
using __aarch64__.)
NOTE: This change is based on below TFA commit

Parallel builds would fail while generating the dependency file of the
first source file that included tests_list.h due to it missing.
In-order builds only worked, because a rule that specified tests_list.c
as a prerequisite happened to get executed first.
This patch introduces tests_list.h as an order-only dependency of all
rules that generate dependency files. This is necessary because we can't
know which files actually depend on it until the dependency files have
been generated.
This forces the autogenerated files to be generated before any other
files are compiled, but does not cause unrelated files to recompile if
they are modified.

This prevents the execution of the read-only data.
This is done in a similar way in TF-A when the build flag
SEPARATE_CODE_AND_RODATA is enabled.
The build flag is probably not needed in TF-A Tests.

Add -mstrict-align flag, and -march minor version. These are needed to
prevent compilers generating unaligned accesses and enable
architectural features respectively.
Enable the SCTLR.A and SCTLR.SA alignment checks in all images.
TF test has several cases of code which enable the alignment checks.

Enforce full include path for includes.
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 with the same name).

'fid' (short for 'function ID') makes for a more explicit name.

BL1 SMC function IDs are not platform-specific so move them to a new
generic header file, called bl1.h.

At the moment, alignment fault checking is always enabled in TF-A
Tests (by setting the HSCTLR/SCTLR.A bit). Thus, for every instruction
that loads or stores one or more registers, the hardware checks that
the address being accessed is properly aligned to the size of the data
element(s) being accessed. If this check fails it causes an alignment
fault, which is taken as a data abort exception.
However, the compiler is currently unaware that it must not emit load
and store instructions resulting in unaligned accesses because we do
not compile the source code with -mstrict-align (AArch64) /
-mno-unaligned-access (AArch32). Because of this, we might get some
unexpected alignment faults.
We could request the compiler to align all data accesses but whether
this gives us any performance benefit is dependent on the
microarchitecture. Thus, it is simpler to just disable hardware
alignment checking and let the compiler make the call.

In practice, all the functions in this file are platform-specific. It is
better to force all platforms to implement than having some sort of weak
function placeholder.
