virtio: features, fixes

vdpa generic device type support
 More virtio hardening for broken devices
 On the same theme, revert some virtio hotplug hardening patches -
 they were misusing some interrupt flags, will have to be reverted.
 RSS support in virtio-net
 max device MTU support in mlx5 vdpa
 akcipher support in virtio-crypto
 shared IRQ support in ifcvf vdpa
 a minor performance improvement in vhost
 Enable virtio mem for ARM64
 beginnings of advance dma support
 
 Cleanups, fixes all over the place.
