Prior to QEMU v3.1.0, QEMU generated the 'virt' SoC node with a "riscv-virtio-soc" compatible string, and a "simple-bus" driver was created to accommodate that special case in U-Boot. Starting from QEMU v3.1.0, the SoC node was set as a "simple-bus", hence the special simple-bus driver is no longer needed. Update the doc to mention the latest tested QEMU version 4.2.0.
