powerpc/perf: update attribute_group data structure
Rename the power_pmu and attribute_group variables that support PowerISA v2.07. Add a cpu feature flag check to pick the PowerISA v2.07 format structures to support. Signed-off-by: Madhavan Srinivasan <maddy@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
