Balint Dobszay cbf9e84a19 plat/arm/fvp: Support performing SDEI platform setup in runtime
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.

Madhukar Pappireddy 4682461ded 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.

Madhukar Pappireddy 0ad5b318f7 Fix topology description of cpus for DynamIQ based FVP
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.

Balint Dobszay 2d51b55ee5 Replace dts includes with C preprocessor syntax
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.

Roberto Vargas e230f4d54d Remove dtc warnings
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.

Jeenu Viswambharan 1bdbdc3b3f Add Linux DTS for FVP with threaded CPUs
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.
