arch/microblaze: 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. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
