When all cores in a cluster are powered down the parent cluster can
be also powered down. When the last core has requested powering down
follow by sending the cluster power down sequence to the system
power controller firmware.

The MSMC port defines were added to help in the case when some ports
are not connected and have no cores attached. We can get the same
functionality by defined the number of cores on that port to zero.
This simplifies several code paths, do this here.

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.

While it would be useful to have a device tree based build, the
required components are not in place yet, so support just a simple
statically defined configuration to begin with.
