BOOT MODE (BAM) for EMS S8 e CRD2

We have added new BOOT MODE (BAM) for complete control unit management on SCANIA:
 - CONTINENTAL EMS S8

 and new BOOT MODE (BAM) for MERCEDES BENZ / FCA with control units:
 - DELPHI CRD2.xx (Versioni SOLENOID e PIEZOTEC)

 This makes reading and writing ECU in open mode easier
 compared to the previous JTAG mode (JTAG function still available).
 Furthermore, with this method, it's no longer necessary for Delphi CRD2.xx SOLENOIDs to open the ECU from the underside.
