Some recent enhancements to EL3 runtime firmware like support for save and restoring GICv3 register context during system_suspend necessitates additional data memory for the firmware. This patch introduces support for creating a TZC secured DDR carveout for use by ARM reference platforms. A new linker section `el3_tzc_dram` is created using platform supplied linker script and data marked with the attribute `arm_el3_tzc_dram` will be placed in this section. The FVP makefile now defines the `PLAT_EXTRA_LD_SCRIPT` variable to allow inclusion of the platform linker script by the top level BL31 linker script.
