[PATCH 1/1] virtio: Add uvirtio driver

This is for testing purpose to create virtio devices from user space. uvirtio-vga.c shows how to create a virtio-vga device. Currently we don't have a use case which requires user/kernel communication so read/write api hasn't been implemented. Signed-off-by: Lepton Wu --- drivers/virtio/Kconfig
