hw/arm/virt: introduce DEFINE_VIRT_MACHINE_AS_LATEST

Browse Source 
Create two variants of DEFINE_VIRT_MACHINE. One, just called
DEFINE_VIRT_MACHINE, that does not set properties that only
the latest machine type should have, and another that does.
This will hopefully reduce potential for errors when adding
new versions.
