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
