    xen: avoid generation of empty asm/iommu.h
    
    asm/iommu.h shouldn't need to be included when CONFIG_HAS_PASSTHROUGH
    isn't enabled.
    As <asm/iommu.h> is ifdef-ed by CONFIG_HAS_PASSTHROUGH it should
    be also ifdef-ed field "struct arch_iommu arch" in struct domain_iommu
    as definition of arch_iommu is located in <asm/iommu.h>.
    
    These amount of changes are just enough to avoid generation of empty
    asm/iommu.h for now.
