Grant Likely cb6dc512b7 arch/powerpc: Move dma_mask from of_device into pdev_archdata
By moving dma_mask into pdev_archdata, and adding archdata to
struct of_device, it makes it possible to substitute of_device
with struct platform_device, which is a stepping stone to
removing the of_platform bus entirely.
