virtio: Add virtio over mmio transport driver
VirtIO can use various different buses and virtio devices are
commonly implemented as PCI devices. But virtual environments
without PCI support (a common situation in embedded devices
models) might use simple memory mapped device (“virtio-mmio”)
instead of the PCI device.
This adds a transport driver that implements UCLASS_VIRTIO for
virtio over mmio.
