This patch switches machine types to provide device-tree cpu ids.
We have three cases to handle:
- pseries < 2.7 call ppc_cpu_init() and should compute the DT id as it is
currently done in the target code.
- pseries 2.7 don't call ppc_cpu_init() and compute the DT as the sum of
the core DT id and the the thread index within the core
- all other machine types don't support SMT and just need to provide a
different index for each vcpu
