iommu/amd: Use AMD specific data structure for irq remapping
For compatibility reasons the irq remapping code for the AMD IOMMU used the same per-irq data structure as the Intel implementation. Now that support for the AMD specific data structure is upstream we can use this one instead. Reviewed-by: Shuah Khan <shuahkhan@gmail.com> Signed-off-by: Joerg Roedel <joro@8bytes.org>
