This converts powerpc to use the generic pci_set_dma_mask and pci_set_consistent_dma_mask (drivers/pci/pci.c).
The generic pci_set_dma_mask does what powerpc's pci_set_dma_mask does.
Unlike powerpc's pci_set_consistent_dma_mask, the gneric pci_set_consistent_dma_mask sets only coherent_dma_mask. It doesn't work for powerpc? pci_set_consistent_dma_mask API should set only coherent_dma_mask?
