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.

This patch adds a per-soc system reset handler for Tegra chips. The
handler gets executed before the actual system resets. This allows
for custom handling of the system reset sequence on each SoC.

The validate_power_state() handler checks the power_state for a valid afflvl
and state id. Although the afflvl check is common, the state ids are implementation
defined.

This patch moves the handler to the tegra/soc folder to allow each SoC to validate
the power_state for supported parameters.

This patch implements the get_sys_suspend_power_state() handler required by
the PSCI SYSTEM_SUSPEND API. The intent of this handler is to return the
appropriate State-ID field which can be utilized in `affinst_suspend()` to
suspend to system affinity level.

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.
