Varun Wadekar 71cb26ea5b Tegra: remove support for legacy platform APIs
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.

Varun Wadekar 3b40f993f4 Tegra: introduce per-soc system reset handler
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.

Varun Wadekar 93eafbcad4 Tegra: implement per-SoC validate_power_state() handler
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.

Varun Wadekar 94c672e77f Implement get_sys_suspend_power_state() handler for Tegra
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.

Varun Wadekar 08438e24e1 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.
