Use full include paths like it is done for common includes.

This cleanup was started in commit d40e0e08283a ("Sanitise includes
across codebase"), but it only cleaned common files and drivers. This
patch does the same to Arm platforms.

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 ARM_PLAT_MT bit enables the support for MT bit in
MPIDR format. This means that the level 0 affinity
represents the thread and CPU / Cluster levels are
at affinity level 1 and 2 respectively.
This was not catered for in the scpi 'css_scp_get_power_state, API.
Since the SCPI driver can only cater for single threaded CPUs,
this patch fixes the problem by catering for this shift by
effectively ignoring the Thread (level 0) affinity level.

If there is a pending interrupt, it is possible for the AP to come out
of the final WFI before SCP has a chance to act on it.  Prevent this
by disabling the GIC CPU interface before issuing a WFI.

Previously, SCP would not wait on WFI before taking an action but
would shut down the core or system regardless.

This patch introduces an additional layer of abstraction between
CSS power management hooks and the SCPI driver. A new set of APIs
are introduced in order to abstract out power management operations
from underlying communication mechanism with the SCP.

The SCPI and the associated MHU drivers are moved into a `drivers`
folder in CSS. The new SCP communication abstraction layer is added
in the `drivers/scp` folder. The existing CSS power management
uses the new APIs to reflect this abstraction.
