HAVE_PERF_EVENTS_NMI is used for two things - the oprofile NMI timer
and the hard lockup detector.
Create HAVE_OPROFILE_NMI_TIMER so an architecture can select them
separately. On ppc64 we want to add the hard lockup detector, but not
the oprofile NMI timer fallback.

Resending, because I forgot to cc the x86 guys.
How would you like us to handle it? Michael Ellerman says
we can put it in a topic branch, or just merge it and cop
any conflicts.
