[XEN][POWERPC] Fix Xen-GDB Stub (smp_sen_stop, E00 on unknown command, remove 
printk prefix)
- Remove BUG() from smp_stop_all(), common code changes added a call to this - 
changed to unimplemented().
- remove the printk prefix "(XEN) " when falling into gdb, because gdb tried to parse the 
"(XEN) " response sometimes
- return E00 on unknown command (thx to jimi)
