virtio: Add a Sandbox transport driver

This driver provides support for Sandbox implementation of virtio
transport driver which is used for testing purpose only.

Two drivers are provided. The 2nd one is a driver that lacks the
'notify' op.

virtio: pci: Support non-legacy PCI transport device

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.

It only supports the legacy interface of the pci transport, which

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.

dm: Add a new uclass driver for VirtIO transport devices

This adds a new virtio uclass driver for “virtio” [1] family of
devices that are are found in virtual environments like QEMU,
yet by design they look like physical devices to the guest.

The uclass driver provides child_pre_probe() and child_post_probe()
methods to do some common operations for virtio device drivers like
device and driver supported feature negotiation, etc.
