arm64: dma-mapping: Attach IOMMUs as groups

Some devices behind IOMMUs might end up in IOMMU groups due to DMA
aliasing.  The iommu_attach_device API expects a single device in a
group all by its lonesome, so it fails when a device is passed in that's
part of a group.  Use iommu_attach_group to accommodate these types of
devices.
