Single-step interrupts are suppressed if the nip is between 0x100 and 0xf00. This has been the case for a long time and it's not clear what the intention is. Likely either an attempt to suppress trace interrupts for instructions that cause an interrupt on completion, or a workaround to prevent software tripping over itself single stepping its interrupt handlers. BookE interrupt vectors are set by IVOR registers, and BookS has AIL modes and new interrupt types, so there are many interrupts including the debug interrupt which can be outside this range. So any effect it might have had does not cover most cases (including Linux on recent BookS CPUs). Remove this special case.
