intel_iommu: Check compatibility with host IOMMU capabilities
If check fails, host device (either VFIO or VDPA device) is not
compatible with current vIOMMU config and should not be passed to
guest.
Only aw_bits is checked for now, we don't care about other caps
before scalable modern mode is introduced.
