vDPA/ifcvf: fetch device feature bits when probe
...
This commit would read and store device feature
bits when probe.
rename ifcvf_get_features() to ifcvf_get_hw_features(),
it reads and stores features of the probed device.
new ifcvf_get_features() simply returns stored
feature bits.

net/vdpa: Use struct for set/get vq state
...
For now VQ state involves 16 bit available index value encoded in u64
variable. In the future it will be extended to contain more fields. Use
struct to contain the state, now containing only a single u16 for the
available index. In the future we can add fields to this struct.

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.
