[PATCH V5 RESEND 2/3] iommu/hisilicon: Add hi6220-SoC smmu driver

Add iommu driver for hi6220 SoC platform.The smmu on hi6220 SoC is for media system.And the media IP use the same page-table. It supports only one-to-one mapping from iova to phys address. Signed-off-by: Chen Feng --- drivers/iommu/Kconfig| 11 +
