Rashmica Gupta	2d59b3b256	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.

Denis Kirjanov	39fcfb911c	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).
