[PATCH] s390: hangcheck timer support

Remove useless s390 define from hangcheck-timer, remove wrong definition of a
TOD second and other s390 ifdefs.  Use monotonic_clock instead.

Add hangcheck-timer option, copied from drivers/char/Kconfig.  This is ugly
but unless we have a big Kconfig cleanup we cannot include
drivers/char/Kconfig...
