When using device tree dms resources are not obtained via IORESOURCE_DMA.
As a result, we would get warning even though DMA was working.

This fixes the problem by checking for dev.of_node and skipping trying to
get the dma platform resource if we are using device tree.

Actually, with Peter's series adding dma_slave_map[] for all
mach-davinci platforms, this code should not be needed at all. Can you
try that dropping the platform_get_resource() calls for DMA works with
linux-next?
