hw/arm/virt: Support legacy -nic command line syntax 

Support the legacy -nic syntax for creating PCI network devices
as well as the new-style -device options. This makes life easier
for people moving from x86 KVM virtualization to ARM KVM virtualization
and expecting their network configuration options to work the same
way for both setups.

We use "virtio" as the default NIC model if the user doesn't specify one.
