Tegra: handlers for common and SoC-specific SiP calls

This patch implements a handler for common SiP calls. A weak
implementation for the SoC-specific handler has been provided
which can be overridden by SoCs to implement any custom SiP
calls.

Migrate platform ports to the new xlat_tables library

This patch modifies the upstream platform port makefiles to use the new
xlat_tables library files. This patch also makes mmap region setup common
between AArch64 and AArch32 for FVP platform port. The file `fvp_common.c`
is moved from the `plat/arm/board/fvp/aarch64` folder to the parent folder
as it is not specific to AArch64.

In order to handle secure/non-secure interrupts, overload the plat_ic_*
functions and copy GIC helper functions from arm_gic.c. Use arm_gic.c
as the reference to add Tegra's GIC helper functions.

Now that Tegra has its own GIC implementation, we have no use for
plat_gic.c and arm_gic.c files.

Reserve a Video Memory aperture in DRAM memory

This patch adds support to reserve a memory carveout region in the
DRAM on Tegra SoCs. The memory controller provides specific registers
to specify the aperture's base and size. This aperture can also be
changed dynamically in order to re-size the memory available for
DRM video playback. In case of the new aperture not overlapping
the previous one, the previous aperture has to be cleared before
setting up the new one. This means we do not "leak" any video data
to the NS world.

Support for NVIDIA's Tegra T210 SoCs

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.
