Subject: [PATCH] vdpa: move to drivers/vdpa

We have both vhost and virtio drivers that depend on vdpa.
It's easier to locate it at a top level directory otherwise
we run into issues e.g. if vhost is built-in but virtio
is modular.  Let's just move it up a level.

Randy I'd say the issue you are reporting (vhost=y, virtio=m)
is esoteric enough not to require a rebase for this.
So I'd just apply this on top.
Do you agree?
