The Memory Select Switch Controller routes any CPU transactions to
the appropriate slave depending on the transaction address. During
system suspend, it loses all config settings and hence the CPU has
to restore them during resume.

This patch restores the controller's settings for enabling WRAP to
INCR burst type conversions on the master ports, for any incoming
requests from the AXI slave ports.

Tested by performing multiple system suspend cycles.

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.
