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: net: Support non-legacy device
For v1.0 compliant device, it always assumes the member 'num_buffers'
exists in the struct virtio_net_hdr while the legacy driver only
presented 'num_buffers' when VIRTIO_NET_F_MRG_RXBUF was negotiated.
Without that feature the structure was 2 bytes shorter.
Update the driver to support the non-legacy device.

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.

virtio: Add virtio over pci transport driver
This adds a transport driver that implements UCLASS_VIRTIO for
virtio over pci, which is commonly used on x86.
It only supports the legacy interface of the pci transport, which
is the default device that QEMU emulates.

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.
