dt-bindings: virtio: Add binding for virtio devices 



Allow virtio device sub-nodes to be added to the virtio mmio or pci
nodes. The compatible property for virtio device must be of the format
"virtio,device<ID>", where ID is virtio device ID in hexadecimal format.

description:

  These bindings are applicable to virtio devices irrespective of the bus they

  are bound to, like mmio or pci.



# We need a select here so we don't match all nodes with 'virtio,mmio'

  compatible:

    pattern: "^virtio,device[0-9a-f]{1,8}$"

    description: Virtio device nodes.

      "virtio,deviceID", where ID is the virtio device id. The textual

      representation of ID shall be in lower case hexadecimal with leading

      zeroes suppressed.
