config: introduced new CONFIG_MCSI_MODEM preprocessor symbol All MCSI functionality was previously conditionalized on CONFIG_TARGET_FCMODEM (even earlier it was CONFIG_TARGET_FCDEV3B), but having a dedicated preprocessor symbol for this purpose (defined in targets/*.h as appropriate) makes it much easier to support different modem targets with MCSI enabled.
