firmware/board: introduce new FCDEV3B (FreeCalypso) target

FCDEV3B (stands for "FreeCalypso development board, triband") is a
GSM mobile station development board by FreeCalypso project. The
board features the same legendary TI Calypso GSM MS chipset that
was used in commercial GSM/GPRS modems such as Openmoko's, and
functions as a standalone (or "bare") GSM modem.

For more information, please see the project's web side:
