Supports vdpa-dev-pci, we can use the device as follow:

-device vhost-vdpa-device-pci,vhostdev=/dev/vhost-vdpa-X

The following patch moved the virtio-pci.h to the include/ directory:

e1b1f53 2022-05-16 04:38:40 -0400 hw/virtio: move virtio-pci.h into 
shared include space

I'll rebase this series recently.

Thanks.
