powerpc/eeh: Fetch IOMMU table in reliable way
Function eeh_iommu_group_to_pe() iterates each PCI device to check
the binding IOMMU group with get_iommu_table_base(), which possibly
fetches pdev->dev.archdata.dma_data.dma_offset. It's (0x1 << 59)
for "bypass" cases.
The patch fixes the issue by iterating devices hooked to the IOMMU
group and fetch IOMMU table there.
