libvirt v5.3.0 with QEMU 4.0.0 use PCI automatically and thus storage
is connected via PCI, which is not visible to U-Boot automatically.
Refactor to do "pci enum" followed by "virtio scan" to see PCI
connected storage.
Tested with Fedora/RISCV using the latest releases: libvirt 5.4.0,
QEMU 4.0.0 and U-Boot 2019.07 RC4.
