fix(bl1): prevent null pointer dereference

Added an assertion to ensure ptr is not NULL before
dereferencing it. This prevents potential null pointer

Merge "Switch AARCH32/AARCH64 to __aarch64__" into integration

Switch AARCH32/AARCH64 to __aarch64__

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__.)

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.

Ensure the flow through switch statements is clear

Ensure case clauses:
* Terminate with an unconditional break, return or goto statement.
* Use conditional break, return or goto statements as long as the end
of the case clause is unreachable; such case clauses must terminate
with assert(0) /* Unreachable */ or an unconditional __dead2 function
call
* Only fallthough when doing otherwise would result in less
readable/maintainable code; such case clauses must terminate with a
/* Fallthrough */ comment to make it clear this is the case and
indicate that a fallthrough is intended.

This reduces the chance of bugs appearing due to unintended flow through a
switch statement
