Ported the memory guard debug feature to coldfire, using the breakpoint logic. There are 3 shortcomings compared to SH1: (1) While the setting itself survives RoLo, it cannot be read back because the debug module programming model is write only. (2) system_reboot() from a 'Debug' exception doesn't work because the CPU enters emulation mode, and the only way leaving this mode is via an rte instruction. (3) (fixable) Catching write accesses to the flash doesn't actually do anything because the flash memory area is set write protected in CSMR2, so a write attempt stalls the bus. * Cosmetic changes in system.c
