[GIT PULL] vhost,vdpa,virtio: cleanups, fixes

Was holding out for a couple of big new features including vop and rpmsg support for 1.0, but it looks like they won't make it in time. virtio i2c might be ready soon but that's a new driver so if it's ready soon it's probably ok to merge outside the merge window ... we'll see. The following

This patch introduces a new ioctl for vhost-vdpa device that can report the iova range by the device. For device that implements get_iova_range() method, we fetch it from the vDPA device. If device doesn't implement get_iova_range() but depends on platform IOMMU, we will query via
