From: Maksim Kostin <maksim.kos...@ispras.ru>
ppce500_reset_device_tree is registered for system reset, but after
c4b075318eb1 this function rerandomizes rng-seed via
qemu_guest_getrandom_nofail. And when loading a snapshot, it tries to read
EVENT_RANDOM that doesn't exist, so we have an error:
qemu-system-ppc: Missing random event in the replay log
To fix this, use qemu_register_reset_nosnapshotload instead of
qemu_register_reset.
