425a507023 vdpa: allow a 32 bit vq alignment 
get_vq_align returns u16 now, but that's not enough for
systems/devices with 64K pages. All callers assign it to
a u32 variable anyway, so let's just change the return
value type to u32.

c9b9f5f8c0 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.
