FUJITA Tomonori 710224fa27 arm: fix "arm: fix pci_set_consistent_dma_mask for dmabounce devices" 
This fixes the regression caused by the commit 6fee48cd33
("dma-mapping: arm: use generic pci_set_dma_mask and
pci_set_consistent_dma_mask").

ARM needs to clip the dma coherent mask for dmabounce devices. This
restores the old trick.

Note that strictly speaking, the DMA API doesn't allow architectures to do
such but I'm not sure it's worth adding the new API to set the dma mask
that allows architectures to clip it.
