Matias Ezequiel Vara Larsen 083082a4e6 can: virtio: Add virtio CAN driver 
Add virtio CAN driver based on Virtio 1.4 specification (see
https://github.com/oasis-tcs/virtio-spec/tree/virtio-1.4). The driver
implements a complete CAN bus interface over Virtio transport,
supporting both CAN Classic and CAN-FD Ids. In term of frames, it
supports classic and CAN FD. RTR frames are only supported with classic
CAN.

Usage:
- "ip link set up can0" - start controller
- "ip link set down can0" - stop controller
- "candump can0" - receive frames
- "cansend can0 123#DEADBEEF" - send frames
