powerpc/cputable: Fix oprofile_cpu_type on power8
Maynard informed me that neither the oprofile kernel module nor oprofile userspace has been updated to support that "legacy" oprofile module interface for power8, which is indicated by "ppc64/power8." 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.
