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.
