This patch fixes static checks errors reported for missing copyright in
`include/dt-bindings/interrupt-controller/arm-gic.h` and the include
order of header files in `.dts` and `.dtsi` files.

The Arm Generic Timer specification mandates that the
interrupt associated with each timer is low level triggered,
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\
fvp-base-gicv3-psci-common.dtsi
fvp-base-gicv3-psci-aarch32-common.dtsi
fvp-base-gicv2-psci-aarch32.dts
fvp-base-gicv2-psci.dts
fvp-foundation-gicv2-psci.dts

describe interrupt types as edge rising
IRQ_TYPE_EDGE_RISING = 0x01:
interrupts = <1 13 0xff01>,
<1 14 0xff01>,
<1 11 0xff01>,
<1 10 0xff01>;
, see include\dt-bindings\interrupt-controller\arm-gic.h:
which causes Linux to generate the warnings below:
arch_timer: WARNING: Invalid trigger for IRQ5, assuming level low
arch_timer: WARNING: Please fix your firmware
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.

Using the fconf framework, the Group 0 and Group 1 secure interrupt
descriptors are moved to device tree and retrieved in runtime. This
feature is enabled by the build flag SEC_INT_DESC_IN_FCONF.

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.

This patch introduces dynamic configuration for SDEI setup and is supported
when the new build flag SDEI_IN_FCONF is enabled. Instead of using C arrays
and processing the configuration at compile time, the config is moved to
dts files. It will be retrieved at runtime during SDEI init, using the fconf
layer.

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.

DynamIQ based designs have upto 8 CPUs in each cluster. This
patch fixes the device tree node which describes the topology
of the CPU for DynamIQ FVP Model.

Using the /include/ syntax, the include was evaluated by dtc, only after running
the preprocessor, therefore the .dtsi files were not preprocessed. This patch
adds the #include syntax instead. Evaluating this and preprocessing the files
now happens in a single step, done by the C preprocessor.

DTC generates warnings when unit names begin with 0, or
when a node containing a reg or range property doesn't have a unit name
in the node name. This patch fixes those cases.

In contrast with the non-multi-threading DTS, this enumerates MPIDR
values shifted by one affinity level to the left. The newly added DTS
reflects CPUs with a single thread in them.
Since both DTS files are the same apart from MPIDR contents, the common
bits have been moved to a separate file that's then included from the
top-level DTS files. The multi-threading version only updates the MPIDR
contents.
