This reverts this change and uses oprofile_type instead. Perf now works on POWER8 again and oprofile will revert to using timers on POWER8. Kudos to mpe this fix.

This results in no samples. The solution is to default to the "timer" type, instead. The raw entry also should be updated, as "ppc64/ibm-compat-v1" indicates to oprofile userspace to use "compatibility events" which are obsolete in ISA 2.07.
