By default QEMU creates legacy PCI transport devices, but we can ask QEMU to create non-legacy one if we pass additional device property/value pairs in the command line:
-device virtio-blk-pci,disable-legacy=true,disable-modern=false
This adds a new driver driver to support non-legacy (modern) device mode. Previous driver/file name is changed accordingly.

Applied to u-boot-dm/next, thanks!
