This patch adds support for Total Compute (TC0) platform. It is an
initial port and additional features are expected to be added later.

TC0 has a SCP which brings the primary Cortex-A out of reset
which starts executing BL1. TF-A optionally authenticates the SCP
ram-fw available in FIP and makes it available for SCP to copy.

Some of the major features included and tested in this platform
port include TBBR, PSCI, MHUv2 and DVFS.

This patch fixes wrong ID_AA64DFR0_EL1 register read instead of
ID_AA64PFR0_EL1 to detect support for MPAM extension.
It also implements get_mpam_version() function which returns
MPAM version as:
0x00: None Armv8.0 or later;
0x01: v0.1 Armv8.4 or later;
0x10: v1.0 Armv8.2 or later;
0x11: v1.1 Armv8.4 or later;

SPCI is renamed as PSA FF-A which stands for Platform Security
Architecture Firmware Framework for A class processors.
This patch replaces the occurrence of SPCI with PSA FF-A(in documents)
or simply FFA(in code).

This patch introduces the populate function which leverages
a new driver to extract base address and clk frequency properties
of the uart serial node from HW_CONFIG device tree.

This patch also introduces fdt helper API fdtw_translate_address()
which helps in performing address translation.

This patch enables SDEI support for all Tegra platforms, with
the following configuration settings.

* SGI 8 as the source IRQ
* Special Private Event 0
* Three private, dynamic events
* Three shared, dynamic events

This patch enables the v8.6 extension to add a delay before WFE traps
are taken. A weak hook plat_arm_set_twedel_scr_el3 has been added in
plat/common/aarch64/plat_common.c that disables this feature by default
but platform-specific code can override it when needed.

The only hook provided sets the TWED fields in SCR_EL3, there are similar
fields in HCR_EL2, SCTLR_EL2, and SCTLR_EL1 to control WFE trap delays in
lower ELs but these should be configured by code running at EL2 and/or EL1
depending on the platform configuration and is outside the scope of TF-A.

This patch adds support for passing FVP platform's topology
configuration to DTS files for compilation, which allows to
build DTBs with correct number of clusters and CPUs.
This removes non-existing clusters/CPUs from the compiled
device tree blob and fixes reported Linux errors when trying
to power on absent CPUs/PEs.
If DTS file is passed using FVP_HW_CONFIG_DTS build option from
the platform's makefile, FVP_CLUSTER_COUNT, FVP_MAX_CPUS_PER_CLUSTER
and FVP_MAX_PE_PER_CPU parameters are used, otherwise CI script will
use the default values from the corresponding DTS file.
