The BL2 fills in the UART controller ID to be used as the normal as
well as the crash console on Tegra platforms. The controller ID to
UART controller base address mapping is handled by each Tegra SoC
the base addresses might change across Tegra chips.
This patch adds the handler to parse the platform params to get the
UART ID for the per-soc handlers.

This patch moves the definition for `plat_get_syscnt_freq()`
from arm_bl31_setup.c to arm_common.c. This could be useful
in case a delay timer needs to be installed based on the
generic timer in other BLs.
This patch also modifies the return type for this function
from `uint64_t` to `unsigned long long` within ARM and other
platform files.

This patch modifies the Tegra port to support the new platform
APIs so that we can disable the compat layer. This includes
modifications to the power management and platform topology code.

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.
