"powerpc/iommu: Cleanup setting of DMA base/offset" expects that
the default DMA offset is set from pnv_ioda_setup_bus_dma() which
is correct unless it is SRIOV where the code flow is different - at
the moment when pnv_ioda_setup_bus_dma() is called, there is no PE for
the just created VF.
This adds missing set_dma_offset() to pnv_pci_ioda_dma_dev_setup()
to cover the case of SRIOV.
Note that we still need set_dma_offset() in pnv_ioda_setup_bus_dma()
as at the boot time pnv_pci_ioda_dma_dev_setup() is called when no PE
was created yet, this happens at the PHB fixup stage.

Makes sense to squash it to "powerpc/iommu: Cleanup setting of DMA base/offset".
