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.
