imx: Fix missing inclusion of cdefs.h

This was found by compiling with -fno-common:

./build/picopi/release/bl2/imx_snvs.o:(.bss.__packed+0x0): multiple definition of `__packed';
./build/picopi/release/bl2/imx_caam.o:(.bss.__packed+0x0): first defined here

__packed was intended to be the attribute macro from cdefs.h, not an
object of the structure type.

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.

Standardise header guards across codebase

All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.

The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.

The exceptions are files that are imported from other projects:

- CryptoCell driver
- dt-bindings folders
- zlib headers

imx: imx_snvs: Define a SNVS header and memory map

This commit defines two things.

- The basic SNVS memory map. At the moment that is total overkill for the
permission bits we need to set inside the SNVS but, for the sake of
completeness define the whole SNVS area as a struct.

- The bits of the HPCOMR register

A permission fix will need to be applied to the SNVS block prior to
switching on TrustZone. All we need to do is waggle a bit in the HPCOMR
register. To do that waggle we first need to define the bits of the
HPCOMR register.

- A imx_snvs_init() function definition

Declare the snvs_init() function so that it can be called from our
platform setup code.
