virtio-mmio: add support for transport version 3
Virtio MMIO transport version 3 allows device reset to complete
asynchronously. Unlike version 2, where writing zero to Status must
complete the reset before the write returns, version 3 requires the
driver to poll Status until it reads back zero before considering reset
complete.
Update virtio-mmio accordingly: accept transport version 3 and, during
reset, wait for Status to become zero. Keep the polling loop unbounded,
consistent with virtio-pci, since the reset callback does not return an
error code.
