ppc: Check the availability of transactional memory
KVM-PR currently does not support transactional memory, and the implementation in TCG is just a fake. We should not announce TM support in the ibm,pa-features property when running on such a system, so disable it by default and only enable it if the KVM implementation supports it (i.e. recent versions of KVM-HV). These changes are based on some earlier work from Anton Blanchard (thanks!).
