fc-target.h preprocessor symbols: introduce CONFIG_TARGET_LEO_RFFE
Out of our currently existing supported targets, Leonardo and Tango
use TI's classic Leonardo RFFE wiring. However, we would like to
use the same quadband RFFE with the same classic wiring on our
FreeCalypso Libre Dumbphone handset, and also on the planned
development board that will serve as a stepping stone toward that
goal. Therefore, we introduce the new CONFIG_TARGET_LEO_RFFE
preprocessor symbol, and conditionalize on this symbol in tpudrv12.h,
instead of a growing || of different targets.
