For monitor "loadvm", we've already done create/initialize/realize
as part of our initial setup of the VM when we started QEMU.
reset is done by load_vmstate() calling qemu_system_reset().

For command line "-loadvm", we do the load_vmstate() after the
initial reset in vl.c.

Either way, VM reloading doesn't need to deal with anything that's
set up in device init/realize as a fixed config, and it doesn't
need to assert IRQ lines either.
