Tegra: handler to check support for System Suspend
...
Tegra210 SoCs need the sc7entry-fw to enter System Suspend mode,
but there might be certain boards that do not have this firmware
blob. To stop the NS world from issuing System suspend entry
commands on such devices, we ned to disable System Suspend from
the PSCI "features".
This patch removes the System suspend handler from the Tegra PSCI
ops, so that the framework will disable support for "System Suspend"
from the PSCI "features".

Tegra: introduce plat_enable_console()
...
This patch introduces the 'plat_enable_console' handler to allow
the platform to enable the right console. Tegra194 platform supports
multiple console, while all the previous platforms support only one
console.
For Tegra194 platforms, the previous bootloader checks the platform
config and sets the uart-id boot parameter, to 0xFE. On seeing this
boot parameter, the platform port uses the proper memory aperture
base address to communicate with the SPE. This functionality is
currently protected by a platform macro, ENABLE_CONSOLE_SPE.

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.

tegra: Fix mmap_region_t struct mismatch
...
Commit fdb1964 ("xlat: Introduce
MAP_REGION2() macro") added a granularity field to mmap_region_t.
Tegra platforms were using the v2 xlat_tables implementation in
common/tegra_common.mk, but v1 xlat_tables.h headers in soc/*/plat_setup.c
where arrays are being defined. This caused the next physical address to
be read as granularity, causing EINVAL error and triggering an assert.
Consistently use xlat_tables_v2.h header to avoid this.
Fixes ARM-software/tf-issues#548.
