[Qemu-ppc] [PATCH v3 4/7] ppc: open code cpu creation for machine types

[Greg Kurz]

If we want to generate cpu_dt_id in the machine code, this must occur
before the cpu gets realized. We must open code the cpu creation to be
able to do this.

This patch just does that.

v3: don't parse cpu features as it is done in a previous patch
