feat(fvp): fdts: add stdout-path to the Foundation FVPs

Add an `stdout-path' property into the `chosen' node of the Foundation
FVPs Devicetrees.

This gives a default console to the Linux kernel when "console=" is not
specified on the kernel command line, which is useful when booting with
U-Boot in UEFI for example.

Plat FVP: Fix Generic Timer interrupt types

The Arm Generic Timer specification mandates that the

see:

Arm Cortex-A76 Core:
"Each timer provides an active-LOW interrupt output to the SoC."

Arm Cortex-A53 MPCore Processor:
"It generates timer events as active-LOW interrupt outputs and
event streams."

The following files in fdts\

IRQ_TYPE_EDGE_RISING = 0x01:

interrupts = <1 13 0xff01>,

, see include\dt-bindings\interrupt-controller\arm-gic.h:

which causes Linux to generate the warnings below:

This patch adds GIC_CPU_MASK_RAW macro definition to
include\dt-bindings\interrupt-controller\arm-gic.h,
modifies interrupt type to IRQ_TYPE_LEVEL_LOW and
makes use of type definitions in arm-gic.h.

FVP: Add support for passing platform's topology to DTS

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.

fconf: Extract topology node properties from HW_CONFIG dtb

Create, register( and implicitly invoke) fconf_populate_topology()
function which extracts the topology related properties from dtb into
the newly created fconf based configuration structure 'soc_topology'.
Appropriate libfdt APIs are added to jmptbl.i file for use with USE_ROMLIB
build feature.

A new property which describes the power domain levels is added to the
HW_CONFIG device tree source files.

This patch also fixes a minor bug in the common device tree file
fvp-base-gicv3-psci-dynamiq-common.dtsi
As this file includes fvp-base-gicv3-psci-common.dtsi, it is necessary
to delete all previous cluster node definitons because DynamIQ based
models have upto 8 CPUs in each cluster. If not deleted, the final dts
would have an inaccurate description of SoC topology, i.e., cluster0
with 8 or more core nodes and cluster1 with 4 core nodes.

Using the /include/ syntax, the include was evaluated by dtc, only after running

adds the #include syntax instead. Evaluating this and preprocessing the files
now happens in a single step, done by the C preprocessor.

Device tree changes to boot FreeBSD on FVPs

FreeBSD does not understand #interrupt-map in a device tree. This prevents the
GIC from being set up correctly. This patch removes the #interrupt-map in the
device trees for the Base and Foundation FVPs. This enables correct boot of
FreeBSD on these platforms.

These changes have been tested with FreeBSD and an Ubuntu cloud image
(ubuntu-16.04-server-cloudimg-arm64-uefi1.img) to ensure compatibility with
Linux.

Add cache topology info to FVP DTBs

From version 4.0 onwards, the ARM64 Linux kernel expects the device
tree to indicate the cache hierarchy. Failing to provide this
information results in the following warning message to be printed by
the kernel:

`Unable to detect cache hierarchy from DT for CPU x`

All the FVP device trees provided in the TF source tree have been
modified to add this information.

to indicate the version as 1.0. The firmware remains
compatible with PSCI v0.2 clients.

* The firmware design guide is updated to document the
APIs supported by the Trusted Firmware generic code.

* The FVP Device Tree Sources (dts) and Blobs(dtb) are also
updated to add "psci-1.0" and "psci-0.2" to the list of
compatible PSCI versions.
