selftests/powerpc: Make reg.h common to all powerpc selftests
Currently there is a reg.h in pmu/ebb that has defines that are useful
in other powerpc selftests so move this up into selftests/powerpc
folder. Also include in utils.h - as this is often used in self tests.
Add in some other useful register defines.

selftests/powerpc: Run EBB tests only on POWER8
EBB (Event Based Branches) are currently only available on POWER8, so we
should skip them on other CPUs.
I've found that at least one test loops forever on 970MP (cycles_with_freeze_test).
