We still treat devices without a DMA mask as defaulting to 32-bits for both mask, but a few releases ago we've started warning about such cases, as they require special cases to work around this sloppyness. Add a dma_mask field to struct platform_device so that we can initialize the dma_mask pointer in struct device and initialize both masks to 32-bits by default, replacing similar functionality in m68k and powerpc. The arch_setup_pdev_archdata hooks is now unused and removed. Note that the code looks a little odd with the various conditionals because we have to support platform_device structures that are statically allocated.
