ARM: davinci: Use platform_device_register_full() to create pdev for dm365's eDMA
Convert the DM365 EDMA platform device creation to use
struct platform_device_info XXXXXX __initconst and
platform_device_register_full()
This will allow us to specify the dma_mask for the device
in an upcoming patch. Without this, EDMA on DM365 refuses
to probe.
