Subject: [PATCH v4 09/25] ARM: davinci: Use platform_device_register_full() to create pdev for eDMA
Convert the eDMA platform device creation to use
struct platform_device_info XXXXXX __initconst and
platform_device_register_full()
This will allow us to cleanly specify the dma_mask for the devices in an
upcoming patch.
