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: e0ea0928 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca339

 ("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 current SPM is a prototype that only supports one secure partition
in EL0. The objective of SPM is to have multiple partitions. The current
MM interface isn't adequate for this, so it is needed to modify heavily
the code to add proper support for it.

However, there are platforms which are already using this (like SGI) and
removing the code would break it.  For this reason, the current SPM code
has been duplicated in order to temporarily preserve compatibility. All
new improvements/changes to SPM will be done in the non-deprecated copy,
that may change without notice.

The new build option SPM_DEPRECATED has been introduced to select the SPM
implementation. It defaults to 1, that selects the deprecated SPM.

Changed the names for consistency with the rest of the library. Introduced
new helpers that manipulate the active translation tables context.

The current internal names are too long, which makes it hard to write
code as many lines overflow the limit and need to be split, which may
not help the reader.

This is done in order to make it easier to read the file spm_main.c.
