iommu/ipmmu-vmsa: Add new IOMMU_DOMAIN_DMA ops
Introduce an alternative set of iommu_ops suitable for 64-bit ARM as well as 32-bit ARM when CONFIG_IOMMU_DMA=y. Also adjust the Kconfig to depend on ARM or IOMMU_DMA. Initialize the device from ->xlate() when CONFIG_IOMMU_DMA=y. Signed-off-by: Magnus Damm <damm+renesas@opensource.se> Signed-off-by: Joerg Roedel <jroedel@suse.de>
