[ARM] Fix PCI_DMA_BUS_IS_PHYS for ARM

PCI_DMA_BUS_IS_PHYS was defined to be zero, which meant we ignored the DMA mask for IDE and SCSI transfers. This is wrong - we have no DMA translation hardware. We want to obey DMA masks so that the block layer performs bouncing itself. Reported-by: Mikael Pettersson <[email protected]> Signed-off-by: Russell King <[email protected]>
