tsar_boot: improving configuration infrastructure

• Using hard_config.h which respects the same sintax that the hard_config.h file of all TSAR platforms. This file can be then generated by the GIET-VM genmap tool or written manually.

• All peripheral drivers have been moved to a drivers directory and they are compiled as a static library. This allows GCC to only include in the final .ELF the object files of used peripherals and not all of them.

• Example hard_config.h and ldscripts have been introduced in the conf directory.

• Improving comments in all files
