Debug interrupt can be either "critical level" or "debug level". There are separate set of save/restore registers used for different level. Example: DSRR0/DSRR1 are used for "debug level" and CSRR0/CSRR1 are used for critical level debug interrupt. Using CPU_FTR_DEBUG_LVL_EXC to decide which interrupt level to be used.
