dma-mapping: powerpc: use generic pci_set_dma_mask and pci_set_consistent_dma_mask
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?
