[POWERPC] 83xx: Make 83xx perfmon support selectable
Not all e300 cores support the performance monitors, and the ones that don't will be confused by the mf/mtpmr instructions. This allows the support to be optional, so the 8349 can turn it off while the 8379 can turn it on. Sadly, those aren't config options, so it will be left to the defconfigs and the users to make that determination.
