Most places we need smp_cpus we use vms->smp_cpus already. This
cleanup makes sure we do everywhere, preparing for the removal
of the global smp_cpus someday.

I'm not sure it's good idea to make/have smp_cpus as ARM specific
machine field.
It should be MachineState.smp_cpus since it's applicable to all machines.
I also fail to see how this patch helps at all as in the end
VirtMachineState.smp_cpus should be converted to MachineState.smp_cpus
and we'd end up changing the same places twice with this patch.
I'd rather see conversion to MachineState.smp_cpus from the beginning.
So suggesting to drop this patch if from this series if it doesn't get
in the way of removing VirtGuestInfo.

All good points. Dropping this patch.
