[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 <mikpe@it.uu.se> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
