[PATCH] powerpc/xmon: Exclude all of xmon/ from ftrace

Exclude core xmon files from ftrace (along with an xmon xive helper outside of xmon/) to minimize impact of ftrace while within xmon. Before patch: root@ubuntu:/sys/kernel/debug/tracing# cat available_filter_functions | grep -i xmon xmon_xive_do_dump xmon_dbgfs_get xmon_print_symbol
