ARM: at91/dma: remove platform data from DMA controller
DMA controller can deduce its configuration data from the platform. Remove the platform data and match device types with the compatible ones. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com> Acked-by: Grant Likely <grant.likely@secretlab.ca>
