* shared/console/reboot.c, shared/start/start.S: Fixed PR#845;
!!enable MMU!! on mvme2100 - this is very important.
Otherwise, all accesses are write-back cached [incl. memory-mapped devices].
(Prerequisite were the changes to shared/startup/bspstart.c just
below.) Implemented rtemsReboot() for mvme2100.
