Arduino Renesas fsp Boards

Recompile libfsp.a

Navigate to extras/e2studioProjects/$projectName
Open the project in e2studio and build it
Launch fsp_to_arduino.sh script; this will
- rebuild the library without .c files in ra_gen
- rename the library and copy in variant/$boardName/libs
- copy the include files (both generated and from fsp) in variant/$boardName/libs
- copy the .c files in ra_gen to variants/$boardName/tmp_gen_c_files/ -> ONLY TEMPORARILY, these files will eventually go away
