targets/fcdev3b.h: bring back CONFIG_TARGET_FCDEV3B C preprocessor symbol CONFIG_TARGET_FCMODEM is no longer used anywhere in our code base, thus it is being fully retired. OTOH, CONFIG_TARGET_FCDEV3B is being brought back: with our earlier FC modem family idea now being withdrawn in light of the discovery of Tango modules, FCDEV3B goes back to being its own unique target.

# This patch applies to the appli_ser_cfg_info initialized data object in the
# init.obj module in main.lib; here we change the default serial configuration
# from RVTMUX on IrDA and F&D on MODEM to RVTMUX on MODEM, nothing on IrDA,
# no F&D available.  This patch will be used as part of the attempt to port
# TCS211 to Mot C139.
