[RFC 3/3] vfio/type1: Increase the version of VFIO_IOMMU_TYPE1_INFO_CAP_IOVA_RANGE

[Eric Auger]

Now the IOVA regions beyond the dma_mask and the vfio aperture are
removed from the usable IOVA ranges, the API becomes reliable to
compute the max IOVA. Let's advertise this by using a new version
for the capability.
