This makes secondary_cpu_reset() unnecessary, so remove it. Also remove setting of cs->halted from cpu_devinit(), which seems out of place when compared to similar code in other architectures (e.g., ppce500_init() in hw/ppc/e500.c). Finally, change creation of CPU object from cpu_create() to object_new() and qdev_realize_and_unref() because cpu_create() realizes the CPU and it's not possible to set a property after the object is realized.
