[Qemu-ppc] [PATCH v2 3/7] ppc: different creation paths for cpus in system and user mode |

StGit/0.17.1-dirty |
The machine code currently uses the same cpu_ppc_init() function to
create cpus as the user mode. This function also triggers the cpu
realization.
It is okay for user mode but with system mode we may want to do other
things between initialization and realization, like generating cpu
ids for the DT for example.
With this patch, each mode has its own creation helper:
- ppc_cpu_init() is for system mode only
- cpu_init() is for user mode only
