In preparation of exposing vITS to domUs, generalize arm_iommu_map_page
and arm_iommu_unmap_page to allow ITS doorbell mappings with dfn != mfn.
The mfn does not need to be passed to guest_physmap_remove_page since
there is no mfn checking on the p2m_iommu_map_{rw,ro} p2m types during
unmap. Pass INVALID_MFN to guest_physmap_remove_page.
