After disabling platform support there's still some more pruning we can do to the virtconfig size, there are a number of drivers and subsystems which are not likely to be useful on mach-virt and so can be disabled in order to further improve build times. Let's do so, noting that having PCI device assignment means that PCI devices might potentially appear. This is just an initial manual passthrough, there will be further savings available especially if we take a much more focused approach.
