vdpa: add driver_override support
`driver_override` allows to control which of the vDPA bus drivers
binds to a vDPA device.
If `driver_override` is not set, the previous behaviour is followed:
devices use the first vDPA bus driver loaded (unless auto binding
is disabled).
Tested on Fedora 34 with driverctl(8):
$ modprobe virtio-vdpa
$ modprobe vhost-vdpa
$ modprobe vdpa-sim-net
$ vdpa dev add mgmtdev vdpasim_net name dev1
# dev1 is attached to the first vDPA bus driver loaded
$ driverctl -b vdpa list-devices
dev1 virtio_vdpa
$ driverctl -b vdpa set-override dev1 vhost_vdpa
$ driverctl -b vdpa list-devices
dev1 vhost_vdpa [*]
Note: driverctl(8) integrates with udev so the binding is
preserved.
