ppc64: Add HTM SPRs support to readelf

Since POWER8, PowerPC 64 supports Hardware Transactional Memory, which has
three special purpose registers associated to it: tfhar, tfiar, and texasr.
This commit add HTM SPRs set as known note type so it's possible to use
'readelf --notes' to inspect the HTM SPRs in a coredump file generated in
such a machines.
