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: https://www.freecalypso.org/fcdev3b.html. Change-Id: I09bd35a18d3ea094000050169a62fd82ba6eccfe Related: OS#3581
