This consists of ensuring that the left operand of each shift is
unsigned when the operation might overflow into the sign bit.

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.

The codebase was using non-standard headers. It is needed to replace
them by the correct ones so that we can use the new libc headers.

This patch introduce TF-A support for NXP's ls1043a platform.
more details information of ls1043a chip and ls1043ardb board
can be found at docs/plat/ls1043a.rst.

Boot sequence on ls1043a is: bootrom loads bl1 firstly, then bl1
loads bl2, bl2 will load bl31, bl32 and bl33, bl31 will boot
bl32(tee os) and bl33(u-boot or uefi), bl33 boot Linux kernel.

Now TF-A on ls1043ardb platform has the following features in this patch:
	* Support boot from Nor flash.
	* TF-A can boot bl33 which runs in el2 of non-secure world.
	* TF-A boot OPTee OS.
	* Support PSCI
