We need to synchronize registers after a reset has been performed. The
current code does that in qemu_system_reset(), load_normal_reset() and
modified_clear_reset() for all vcpus. After SIGP (INITIAL) CPU RESET,
this needs to be done for the targeted vcpu as well, so let's call
cpu_synchronize_post_reset() in the respective handlers.
