Benjamin Herrenschmidt 3514141aed powerpc/pmac: Fix DMA ops for MacIO devices
The macio_dev's created to map devices inside the MacIO ASICs
don't have proper dma_ops. This causes crashes on some machines
since the SCSI code calls dma_map_* on our behalf using the
device we hang from.

This fixes it by copying the parent PCI device dma_ops into
the macio_dev when creating it.
