fconf: necessary modifications to support fconf in BL31 & SP_MIN
Necessary infrastructure added to integrate fconf framework in BL31 & SP_MIN.
Created few populator() functions which parse HW_CONFIG device tree
and registered them with fconf framework. Many of the changes are
only applicable for fvp platform.
This patch:
1. Adds necessary symbols and sections in BL31, SP_MIN linker script
2. Adds necessary memory map entry for translation in BL31, SP_MIN
3. Creates an abstraction layer for hardware configuration based on
fconf framework
4. Adds necessary changes to build flow (makefiles)
5. Minimal callback to read hw_config dtb for capturing properties
related to GIC(interrupt-controller node)
6. updates the fconf documentation
