Oliver O'Halloran 84d8cc0767 powerpc/powernv/pci: Add device to iommu group during dma_dev_setup() 
Historically adding devices to their respective iommu group has been
handled by the post-init phb fixup for most devices. This was done
because:

1) The IOMMU group is tied to the PE (usually) so we can only setup the
   iommu groups after we've done resource allocation since BAR location
   determines the device's PE, and:
2) The sysfs directory for the pci_dev needs to be available since
   iommu_add_device() wants to add an attribute for the iommu group.

However, since commit 30d87ef8b3 ("powerpc/pci: Fix
pcibios_setup_device() ordering") both conditions are met when
hose->ops->dma_dev_setup() is called so there's no real need to do
this in the fixup.

Moving the call to iommu_add_device() into pnv_pci_ioda_dma_setup_dev()
is a nice cleanup since it puts all the per-device IOMMU setup into one
place. It also results in all (non-nvlink) devices getting their iommu
group via a common path rather than relying on the bus notifier hack
in pnv_tce_iommu_bus_notifier() to handle the adding VFs and
hotplugged devices to their group.
