targets: add TARGET_HAS_BUZZER to c11x, c139 and dsample This new target config preprocessor symbol was introduced in Tourmaline in connection with the new approach to playing buzzer melodies via PWT, properly omitting the responsible code on targets where BU output controls the vibrator instead. That code is not present in Magnetite and we have no plans to backport it here, but target header files should be kept consistent between the two trees, especially given that we plan to support FC Venus target in Magnetite.

# 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.
