This patch moves the 'drivers' and the 'lib' folders out of the
'common' folder. This way the 'common' folder shall contain only
the platform support required for all Tegra 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.

Main fixes:
* Fixed if/while statement conditional to be essentially boolean [Rule 14.4]
* Added curly braces ({}) around if/for/while statements in order to
make them compound [Rule 15.6]
* Added explicit casts (e.g. 0U) to integers in order for them to be
compatible with whatever operation they're used in [Rule 10.1]

The PMC Scratch22 register contains the CPU reset vector to
be used by the warmboot code to power up the CPU while resuming
from system suspend. This patch locks this PMC register to avoid
any further writes.

T210 is the latest chip in the Tegra family of SoCs from NVIDIA. It is an
ARM v8 dual-cluster (A57/A53) SoC, with any one of the clusters being active
at a given point in time.
This patch adds support to boot the Trusted Firmware on T210 SoCs. The patch
also adds support to boot secondary CPUs, enter/exit core power states for
all CPUs in the slow/fast clusters. The support to switch between clusters
is still not available in this patch and would be available later.
